Video Transcript for Curt Wiring - Wiring Adapters - C57102 Review
Man: Today we're going to be taking a look at Part Number C57102. This is a Curt Trailer Connector Adapter with a backup alarm. This is 4-way, the 7-way round and 4-way flat. The multi-function vehicle end connector is going to convert any 4-way flat connector vehicle end plug to a combination of a 7-way outlet which is going to be this portion right here. And a 4-pole flat outlet. It's also going to feature the integrated backup alarm and it's going to have three LED lights on there as well. This is designed to connect to a 4-way flat plug on your vehicle.
You're going to have the connection right here to make that appropriate connection. It is going to require additional wiring for the use of brake, power, and accessory leads. All of the brake or . excuse me. All the wires here included in the harness or the adapter are going to have the appropriate connectors on here.
You're going to have three of them that are going to have the butt connectors and then the white is going to be your ground and that's going to have the ring terminal on there that will need be attached with a self-tapping screw. So again this is going to supply your 7-blade RV connector right here as well as a 4-way flat trailer connector. It's going to have the nice dust cap that goes over the connection points to prevent them from any type of corrosion. And then on the 7-way connector it's got the nice spring loaded lid that's going to protect the connection points as well. Now this is going to be constructed of a durable plastic construction. It's going to come with a mounting bracket and the necessary hardware to mount the connector to the actual bracket. You will need the hardware to mount the bracket to the vehicle, that is going to be sold separately.
Through these holes right here that's going to connect using two number 10 half inch self-tapping screws. You can also use a number 10 half inch self-tapping screw to mount the ground connection with the ring terminal here on the end of the white wire. Now to go over the wire functions real fast with you, the yellow wire is going to be for the reverse lights. Your blue wire is going to be for the brakes. The black wire is going to be for 12 volt power and then your white wire is going to be for your ground connection and then you're going to have the four way connector that's going to plug into the existing vehicle 4-way connector. Once you have all those connections made, you're going to have full use of your 7-way connector right here as well as the 4-way flat connector right here. I'm going to show you how it mounts with the bracket.
Just run all the wiring through the slots there, feed your 4-way flat through there as well. Now the holes in the bracket are going to line up perfectly with the holes here on national connector. Now that's going to be able to mount to the rear of your vehicle. It's going to hold it place and you have a little area here on the side of the bracket for your 4-way connector as well so it's going to stay right there next to the 7-way connector. That bracket is going to hold it in place. So real quick I just want to go ahead and show you the function here of the backup alarm. I'm going to go on and make our necessary connections and then you can see how that operates. Sends out a nice strong signal. It's really loud. You'll be able to see the lights flash as well. I'm going to activate the reverse function (beeping sound). That's going to sound and flash anytime the reverse function is activated on your vehicle. That's going to do it for today's review of Part Number C57102. This is the Curt Trailer Connector Adapter with the built in backup alarm. .

Perfect fit with easy installation inst ructions!
by: Kirk05/10/2022
Exactly what I was looking for. Easily connected to my existing 4-way without any additional wiring. The 7-way adapter bracket was the correct size, and the holes were pre-drilled for the right fit to connect to the existing bracket on the (U-Haul Installed) tow bar.

Product is great. Guy on phone made it sound super simple. Now I have to go get the additional pieces and wires to hard wire it in…thought the phone rep should have been more thorough. “Oh, c’mon Jim. Don’t be afraid.” He said nothing about splicing, running wires, circuit breaker or anything.

Sorry about that! This product uses at least 12 gauge wire and butt-connectors to connect the wires to the appropriate functions. Most of the time the colors are in this order but you may have to confirm the function with a circuit tester. Yellow for auxiliary or back-up lights, blue for electric brakes, white for ground, and black for positive power. If you do not need some of the functions, you can secure the wires up using cable ties.

The only complaint is the 4 pin connector falls out of the housing.

- Installation of the Curt Trailer Connector and Back-Up Alarm # C57102 on a 2001 Jeep Grand CherokeeYes, you can connect the yellow wire of the Curt Trailer Connector and Back-up Alarm, # C57102, to the back-up light circuit on your 2001 Jeep Grand Cherokee. Connecting the yellow wire will allow the back-up alarm to activate when you put your Jeep in reverse.
view full answer... - Parts Needed to Install a Brake Controller and 7-Way in a 2012 Lincoln NavigatorYes, the Curt Trailer Connector Adapter # C57102 would be the correct part for you to use to convert your 4-way to a fully functional 7-way. You would just need to run the wires of the # C57102 to those leads. If there isn't a 12 volt power lead you will need to run a 10 gauge wire like part # 10-1-1 through a 40 amp circuit breaker like part # 9510. The brake controller we recommend the most is the Prodigy P2 Brake Controller part # 90885. This is the best selling controller on the market...

- Does the Alarm Always Sound in Reverse on the Curt Trailer Connector Adapter with Backup Alarm?Any time your vehicle is placed in reverse, whether you are towing or not, the alarm will sound on the Curt Trailer Connector Adapter with Backup Alarm item # C57102. To have the same connector without the beeping sound you will want the Curt Trailer Connector Adapter item # C57672. This is the same 7-way and 4-way connector without the alarm. I have linked an installation video below.

You will need enough 12 Gauge Wire # 12-1-1 to run from the 7-way to where you will be tapping into the battery 12 volt source. This is sold by the foot so remember to account for all the bends along your Sportage to get it to your battery source. A Deka Ring Terminal # DW05741-1 will help you to connect to your power supply.

If your Grand Cherokee didn't come with the factory tow package and you're needing to use a brake controller then you will need run a wire from the blue wire on the back of the 7 way up to the engine compartment and through the firewall into the cab of the vehicle. Once it's run through the...

The black wire on # C57102 will connect to the positive battery terminal via a 40 amp circuit breaker # PK54540. The white wire will ground to the vehicle frame. The yellow wire will connect to the reverse light circuit if the trailer has reverse lights. The blue wire will connect to the blue wire from a brake controller. For...

view full answer... - Does the Backup Alarm on Curter Trailer Connector Adapter # C57102 Sound Just when TowingAny time the vehicle is placed in reverse, whether you are towing or not, the alarm will sound. You will have to make sure that yellow wire is connected to a reverse light wire on the vehicle in order for the alarm to function.
view full answer... - Adding a 4- or 7-Way Trailer Connector to a 2017 Chrysler PacificaThe trailer wiring harnesses for the 2017 Chrysler Pacifica do not require identifying the tail light wires and splicing in a harness. There are a couple of options depending on the trim level of your Pacifica. If you have a Limited model use # 118712. And if you have an LX or Touring model use # 118723. Both of the above harnesses are 4-Ways. To add a 7-Way you would first need to install one of them. Then to add a functional 7-Way, retain the 4-Way, and to have the wiring for a brake...

This would give you basically the same kit as the # ETBC7 except with the backup alarm. You wouldn't need the extra wire either. With transmission coolers the best option is to go with the largest one that will fit in the available space in front of the radiator. For example the part # D13503 measures 11" Wide x 8-3/4" tall x 7/8" deep and would...

For an audible alert you can use the Light-Duty to Medium-Duty Back-Up Alarm with Wire Leads # PK41822, the medium to heavy-duty # PK41851, or the integrated alarm in the Curt Trailer Connector Adapter with Backup Alarm - 4-Way to 7-Way RV and 4-Way Flat # C57102.

view full answer... - What are the Wire Functions of the CURT Trailer Connector Adapter, # C57102You are correct. On the CURT Trailer Connector Adapter, # C57102, the white wire is ground, black is for 12 volt power, blue is for brakes, and yellow is for reverse lights. The 4-Way would then just plug into a 4-Way trailer connector on the vehicle to provide the remainder of the lighting functions. Be sure to ground the white wire to the vehicle frame for the connector to function properly.
view full answer... - Does The Curt 7-Way Require a 12 Volt Charge Line To Be Connected When Brake Controller Isn't NeededWhen installing the Curt Trailer Connector Adapter with Backup Alarm # C57102 you will only need to connect the dedicated 12 volt power wire if your trailer requires a power wire. There are several trailers like small pop ups which tie into the 12 volt charge line to maintain power for a refrigerator or heating system and the trailer will not require the operation of brakes. With that said if the trailer has electric brakes you will need to have a controller like the Curt Echo # C51180...
view full answer... - Does Brake Controller Installed on Trailer Require Blue Wire to Be Connected on Tow VehicleSince your trailer already has a brake controller on it you shouldn't need to connect the blue wire from the Curt Trailer Connector Adapter with Backup Alarm # C57102 so you should be able to just cap it off and be fine. I say "should" because any brake controller I've seen that installs on the trailer only requires the standard light functions along with the 12V power. If you can confirm what brake controller you have then I can double check the installation.

The typical locations for this connection point are near the spare tire and also on the drivers side behind the rear tire on the frame rail. This connector will most likely have a dust cover on it and you should be able to remove the cover and the zip ties holding this to the frame and plug it directly into the connector on the rear of the Curt Trailer connector...

To get the 7-way round you will need to install the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat # ETBC7. Both harnesses mentioned are spliced in wiring. This is the only option that we have to get you a 7-way plug on your Volkswagen. You could also contact the dealership directly...

If you don't already have a 4-way connector you will need to add one first. The Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector item # 118467 is custom...
view full answer... - Installing a 7 way Plug On An Australian 1998 Land Rover DiscoveryI do have a potential solution for you. Unfortunately we do not offer any kind of custom wiring kits or adapters you can use for this purpose. What you can do is remove the 7 pin flat plug and splice in a 7 way round plug like the # C57102. In order to separate out the turn signals from the brake lights you would need a converter, # 118158.

The blue wire will go to the brake output signal of your brake controller. The black wire will go to the positive side of your battery through a 40 amp circuit breaker like part # PK54540 The yellow wire will run to the reverse light circuit.

Hopkins does not currently have a back up alarm system that is compatible with this tail light bulb style. If you would like you could use the Curt # C57102 or the #C57101. These are replacment trailer connectors that have also have a back up alarm included. If your trucks currently have a factory installed 7-way you will want to use the # C57101 as a direct replacement. If not...

The first step would be to install a 4 pole trailer connector using part # CU94FR. I've linked to an installation video. The easiest way to proceed from there would be to use an adapter like # 20036. The extra blue wire on the vehicle side would tap into the circuit feeding one of the reverse lamps using the provided quick splice connector. This isn't my favorite, as you'll have an adapter that you'll need to keep track of but if you don't...

For this I recommend the Tekonsha T-One Vehicle Wiring Harness # 118467. This custom harness will simply plug into factory ports located in the rear cargo area on the Outback. I have attached an installation video that you can use for reference. Then with the 4-Way installed (or if you already have one on the vehicle)...

- Where to Tap Into Reverse Light Circuit to Install Trailer Connector Adapter with Backup AlarmTo wire in the reverse light wire on Curt 7-Way connector # C57102 for the back up alarm to work you will need to tap into a reverse light wire behind a reverse light on your 1999 Dodge Ram. If you do not wish to tap into the wire there then you can trace the harness to a more accessible location. Then use a circuit tester such as # PTW2991, to find the correct wire before tapping into it. Be sure that the white ground wire on the 7-Way is attached to the truck frame. Otherwise the harness...
