Expert Answers about Kia Trailer Wiring

• Trailer Wiring for a Motorcycle Towing a Motorcycle Trailer
• Normally, the 5-wire flat connector will accept a 4-wire flat connector and work properly. The extra circuit on the 5-wire connector is normally wired to power a reverse lockout or electric trailer brakes not the brake lights. If your motorcycle has the brake light circuit connected to the extra circuit you will need to do some re wiring or install a converter, item # 119178KIT, on the motorcycle. Your trailer should be wired as follows. White wire = ground, brown = taillight, yellow =...

• Will the 4 Pole to 6 Pole to 4 Pole Trailer Wiring Adapter Work For My Trailer
• The Hopkins 4 Pole to 6 Pole Trailer Wiring Adapter # 37175 will work to connect your vehicle wiring to your trailer wiring. However, you will need the Wiring Kit for Brake Controllers # 5506 to make the adapter fully functional. The 6-way adapter has three wire leads: the blue is for electric brakes, the red wire is the hot lead and the white wire is the ground wire. I attached installation videos of the wiring adapter and wiring kit you may want to check out. There are two standard wiring...

• Can LED Trailer Tail Light # STL56RB Install on 2 Wire Trailer
• The trailer taillight part # STL56RB does use three wires to wire to the trailer wiring. The white is ground, the green is stoplight/turn, and brown is running lights. So sometimes trailer wiring only has two wires and that's because the assemblies used can ground through the mounting hardware. So if your trailer only has 2 wires you'd need to run the ground wire of this assembly to the mounting hardware and you'd be set.

• Will 4 and 7 Way Installation Kit # ETBC7 Work on a 2 Wire Trailer System and 2003 Toyota Tacoma
• Both the Draw-Tite Custom Fit Vehicle Wiring, # 118379, and the 4 and 7 Way Installation Kit, # ETBC7, for your 2003 Toyota Tacoma, will work with a trailer that has a 2 wire system. A two wire system carries the turn signal and brake light signals on the same wire. A 3 wire system has a separate turn signal. Most trailers use a 2 wire system. That is why many trailer harnesses for vehicles with a 3 wire system are made to convert it down to a 2 wire system. The ETBC7 has left turn and...

• Adding Running Lights to Trailer with 5-flat Connector
• It sounds like you have a 5-way flat on your trailer for the lighting functions; running lights, turning and brake and the fifth pin for the reverse lock out on a hydraulic brake coupler. The white wire on the light is the ground function and can be grounded to the trailer frame or spliced into the trailer connector ground wire. The brown wire needs to be wired to the running light circuit. Traditionally, the running light wire on a 5-way is brown but I am not sure which color wire is...

• Can Trailer with Two Running Light Wires Run to Single Brown Wire of Replacement 4-Way
• Yes, you can run the single brown wire of your new 4-way to the 2 brown wires on your trailer. This is actually the most common way 4-ways are wired to trailer since the brown wire (running light circuit) runs down both sides of the trailer.

• Appropriate Wire Gauge For Trailer Wiring
• As long as the THNN wire is copper and the proper gauge for what you are wiring on your trailer you can use it. I have attached a helpful article that explains wiring a trailer and the minimum required wire gauges. We recommend at least 10 gauge wire be used to wire electric brakes like part # 10-1-1. I have attached a link for the wire we carry.

• Ground Wire Location on Trailer For Pollak 6-Pole Connector
• Since different manufacturers can use different color wires you need to test the wires by function and not by color. If there is no white wire present, you can trace the wiring on your trailer to find out where the wires terminate. The wire that is attached to the trailer frame is the ground and should be attached to the 10 o'clock position of the Pollak 6-Pole, Round Pin, Trailer Wiring Connector, part # PK11604. When looking at the connector from the back, the ground would be in the...

• Will the Hopkins 6-Way Trailer Connector Work With the Hopkins Endurance 6-Way Socket
• The Hopkins Trailer Connector, # H20036, will work with the Hopkins Endurance 6-Way Socket, # HM48420. One thing to keep in mind when using these two items is to make sure that you wire the Endurance socket so that it is compatible with the 6-way trailer connector. There are two different ways to wire a 6-way trailer connector and the main difference is the location of the brake control wire and the 12 volt power wire. I have attached a photo that shows how you should wire the Endurance...

• Wiring Electric Brakes to Trailer Without Access to 7-Pin Wiring on Trailer
• Yes, it doesn't matter which wire is ground and which one is the power wire coming from the brake assemblies. If you have a brake wire on each side of the trailer, you do not have to splice. You can use a brake wire for each side. Since the trailer is aluminum you cannot just ground to the frame because it does not conduct electricity well. The aluminum trailer probably has a hard metal core which is why the manufacturer was able to ground into the frame with screws. You won't be able...

• 4-Pole to 7-Way Wiring Adapter 37185 Connection for 2007 Ford F-150 and 1978 Terry Travel Trailer
• The Hopkins 4-Pole to 7-Pole adapter # 37185 you mentioned is not a vehicle-specific product; it can be used on any vehicle with 4-pole wiring to allow upgrading to the 7-way format that includes additional circuits for a trailer's brakes, 12V power and reverse lights. If your 2007 Ford F-150 has 4-pole wiring this item can be used to allow making those additional circuit connections. The linked image shows how the additional wires/circuits on this item are usually configured. The wire...

• Is White Wire of Trailer Wiring Most Commonly the Ground Circuit
• For trailer wiring the white wire is almost always the ground wire circuit. Since trailer wiring gets redone periodically it's not uncommon for the colors of the wiring to get changed but in general white being ground is the most consistent. Then the brown would be most likely the running light circuit. I attached a link to a page that has trailer wiring diagrams for you to check out as well.

• How To Replace 4-Way Flat On Trailer That Has 7 Wires To It
• When a 4 flat connector on a trailer has 7 wires it usually means it either has extra grounds or extra tail light wires. Most likely if the extra wires are white then it is ground, if they are brown then they are most likely tail light wires. The only way to know this for sure it to test the wires for function using a 12V battery and a jumper wire. Touch one end of the jumper wire to the positive post of the battery, the touch the other end of the wire to all of the different wires to...

• Replacement Wishbone Trailer Connector To Replace 6-wire Connector
• Your trailer connector is considered a wishbone connector. A wishbone connector splits the running light circuit into two separate wires. Instead of a single brown wire carrying the running light circuit, you have a wire for running lights on the right side of the trailer and another wire for left side running lights. Then you have a wire carrying the left turn/brake light circuit, wire for right turn/brake light circuit and white wire for ground. Since your connector has 6 wires you probably...

• 4-Pole, 5-Pole and Wishbone Style Trailer Wiring
• There are two types of 5-wire flat trailer wiring harnesses; the wishbone style of 4-pole such as # A35W42B which has 4 pins but that has two separate wires connected to the the running light pin so that you have one wire for each side of the trailer; and the 5-wire 5-pin type like # HM47910 which actually has 5 pins, one being for an additional circuit such as a trailer coupler's electric reverse lockout feature. The basic lighting on a trailer requires only a 4-pole hookup; this 4-pin...

• What Wire Does The Yellow Wire With Brown Stripe On My Trailer Connect To
• On the trailer's 5-way connector the yellow wire with brown stripe is most likely a running light circuit but you want to be sure. There is sometimes a yellow/brown wire which is ran down the left side of the trailer for tail lights and a green/brown wire which is ran down the right side of the trailer for tail lights. Since wire color functions may vary depending on the manufacturer you still want to test the wire to determine the function by using a vehicle battery and jumper wire on...

• Can the Taillight Converter part # 118158 Be Used with LED Taillights
• The LED restriction for the # 118158 is for if the converter was being used on a vehicle with LED lights. Basically, it will work if the trailer has LED taillights, but not if the tow vehicle has them. The input side of the box can't use signals from a vehicle with LED taillights, but the output side can. If only the trailer side of the wiring uses LEDs this would work just fine.
