Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C55301 Review

Today we're going to be taking look at part number C55301. This is the Curt T-connector vehicle wiring harness with a four pole flat trailer connector. This product is going to fit 1973 to 1979 Ford F100s, F150s, F250s and F350's. It's going to provide the four way flat trailer connector at the back of your vehicle to power your trailer's signal lights. The unit is compatible to 5,6 and 7 pole adapters. If you don't have those, those are available here on our website and those will be sold separately.

The benefit of this system is that it's going to connect quickly and easily. You don't have to worry cutting or splicing any of your wires. All you have to do is locate the connection point behind the rear bumper. Simply plug in this T connector right here, very simple, it just snaps right into place, then make your ground connection. The ground connection is going to be your white wire with the ring terminal attached to it.

Curt's going to include the self tapping screw to get that secured. Over here on the four way flat connector, it's going to come with a nice dust cap. That's going to protect the connection points when they're not being used. We're going to have about 36 inches of wiring from the back of one plug to the back of the other. The product is made in the USA. It's going to come with very detailed instructions.

It's going to walk you through the installation process step by step. It's going to come with some zip-ties, that way you can secure any excess or slack wiring that you may have. It will make for a pretty tidy appearance. Once installation is complete, the four way connectors going to be stowed beneath the trailer near the trailer hitch. We do recommend using a mounting bracket. That's going to be sold separately.

That's going to help keep the connector secure. We're also going to recommend that you use a small amount of di-electric grease on all your electrical connections. That's just gonna help prevent any corrosion from being able to settle into the connection points. That's going to do it for our review of part number C55301. This is a Curt T-connector vehicle wiring harness with a four pole flat trailer connector. .

Just what I needed to make a seamless splice into the truck for my trailer plug. Quick delivery and a really nice tracking program. Thanks

It is still working and is as it should be. The main thing was the ease of installation.



by:

I recently put a '77 F-100 cab and bed on a 2006 Crown Victoria LX Sport chassis and wanted to add a trailer hitch to it to pull my small utility trailer. Since there is no "Off the shelf" hitch for this setup I had to make my own. This connector is just what I needed to hook up the wiring for the trailer.

Ive used the trailer several times and the wiring connector has worked without issue.



by:

Exactly what I ordered, pigtail is the vehicle end as it should be.



by:

This item fit perfectly. Just unplug the truck bed & insert the "T".
No new connectors or wire cuts & splicing. Telephone conversations were clear and helpful in selecting the part. The grounding instructions were very plain & easy to follow.

I have an old 75 Ford F250 & needed trailer lights. Your plug in wiring is perfect. Everybody else wanted to cut & splice my truck wires - this always ends up badly because of corrosion. Your plug-in is still working great and there was no wiring damage to the truck. I will recommend you to whoever asks & if I need anything for trailers, etc. you will be the first website I check. Thanks again for a perfect fit.

After searching High/Low for a like-product at several local auto parts stores and continually coming up empty-handed, I then took my search efforts to the internet and quickly discovered that etrailer.com had exactly the item I had been searching for. Hooray and Thanks ... etrailer.com!

The T-connector I'd been searching for needed to fit a mid-70's Ford pickup which required a bumper-mount, 7-pole RV receptacle installed. With the advent of parts such as "Curt's T-Connector" ... installing RV plugs is now a painless, hassle-free operation. It's simply plug & play and will not cause damage to the existing wiring harness on your tow vehicle. It's simply the BEST way to ready your vehicle for RV towing.

The personalized service I received from etrailer.com during this sales transaction will keep me coming back as a customer. There is no better place to purchase such parts! Keep up the good work!

This product is a lot better way to get a trailer plug supply on your vehicle, no cutting and splicing your main wire supply, just unplug the master plug match the ends with this plug and join together. Worked perfect on my 1976 Ford F-250. No pictures. Sorry.

Plugged right in and able to wire my camper, yes - camper not trailer, with no alterations to the original wiring harness.



by:
1977 Ford F-100, F-150, F-250, F-350

Product was better than advertised. The four wires were hard wired into the T connector which in my opinion eliminates future problems. Extremely happy with this product and will use this company for any future needs as applicable.



by:

Part showed up quick and works perfect. Glad I didn’t have to splice into my wiring harness.

Excellent product and perfect connection to my truck, no splicing wires or cutting at all, just plug and go.

It can tow up to 10,000lbs with up to 1,000lbs of tongue weight by using a weight distribution hitch. To tow a trailer you will most likely need a hitch like the Gen-Y Adjustable 2-Ball Mount # 325-GH-317 which has a 15" drop. When not towing you can add the Step # GY79VR...

  • Installation Instructions for Prodigy P3 Brake Controller in 1973 Ford F-250
    Thank you for your recent purchase of a Prodigy P3 brake controller # 90195 for your 1973 Ford F-250. You'll use our brake controller installation kit # ETBC7 to install the controller. An article and video are linked to show you the process. If your truck has a 4-pole trailer harness then all you'll need is the controller and install kit, but if you need a 4-pole then you can use kit # C55301 which plugs in (with no cutting or splicing of wires) at the connection point behind rear bumper.

  • Recommended Trailer Hitch Receiver For 1977 Ford F-100
    For your 1977 Ford F-100, the Draw-Tite Max-E-Loader Trailer Hitch Receiver - Custom Fit - Class III - 2" # 41504 will fit with your roll pan bumper. If you need trailer wiring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55301. This is a quick connect to your factory wiring located behind your bumper. For a ball mount, I recommend B&W Tow & Stow 2-Ball Mount - 2" Hitch - 5" Drop, 5-1/2" Rise - 10K - Black # BWTS10037B.

  • Towing Package and B&W Class V Trailer Hitch Fit for a 1977 Ford F-350
    Yes, the B&W Class V Trailer Hitch, # BWHDRH25198, will install on a 1977 Ford F-350, but it was designed for models with a 10 inch deep drop step bumper. The receiver sits lower to allow room for the deep drop bumper. If you have the factory bumper, then you will want part # BWHDRH25122. You will also want to note that the spare tire will have to be lowered to complete the installation. It can be reinstalled, but it will likely have to be re-positioned slightly forward of the hitch....
