What are the colors of the wires that i need to splice into so i can wire my tail light trailer converter wiring harness wire by wire

Hi. Thanks for your question. For the diagram of Tail Light you can visit https://www.reliable-store.com and download the entire workshop manual. It has all the information along with the diagrams for better understanding. Good day!

The wire colors should be Yellow, Black, White and Green. Do not cut or splice anything into this harness. Use the trailer lights Tap connector that is already in the harness. It is located in the left frame rail near the rear bumper. The converter is a plug and play operation. No splicing is needed. Simply unplug the harness at the Tap connector and plug the converter T plug in series with the existing harness.

Follow the wire back up under the hood to see where it is connected. Sometimes there is an external circuit breaker or the wire may go into the fuse box under the hood It just depends on who installed it.

Dark green with red wires the left stop turn signal Dark green with brown is the right stop turn signal Black with yellow is the tail lights.

Test the wires on the car and ID each ones function, brake light, tail light and so on, hook up to the correct wire on the trailer harness which does have a wiring diagram.

Your vehicle CANNOT be wired for a trailer without using the converter box. The only vehicles that do not require a converter box are the vehicles that use the stop lamp bulb as a turn signal. Your vehicle is equipped with SEPARATE stop lamp and turn signal bulbs.

To make the converter box work correctly, it must be wired according to the instructions to BOTH the stop lamps AND the turn lamps. The tail (or PARK) lamps DO NOT go through the converter box.
Your trailer uses the SAME bulb for stop and turn - THIS is the reason you need a converter.

The wire color for both your LEFT TURN and your RIGHT TURN are LIGHT GREEN/TAN. Although the wire colors are the same at the bulb sockets, these are SEPARATE circuits and must be wired to the correct wire at the converter box. (LEFT and RIGHT) The converter box will have an INPUT connection for EACH of these.

The wire color for your STOP lamps is WHITE/TAN. The converter box should only have one INPUT wire that connects to this. It doesn't matter which side of the vehicle you connect this wire to. All of the stop lamps are on the same circuit.

The converter will then have only one wire for LEFT turn and stop (usually YELLOW) this is the wire that needs to go to your trailer connector for left turn and stop.
The RIGHT turn and stop will most likely be GREEN coming out of the converter.

if they have color coded wires that are brown,green,yellow and black then its possible.but i don`t think so.you can buy a trailer wire adapter that just plugs into the car factory wiring so you don`t have to splice(solder) the wires into the car wiring and it will show you the area for the connection and picture.if you don`t want to go that route then the tail light wires colors are brown.the left signal color is yellow and the right is green and the ground wire on the car is black but on the trailer wire harness it is white.

You need to install a 3-2 wire converter. I suggest a CURT 56175 then
1.Using a test lamp, identify the corresponding wires in the harness for the left turn, right turn, tail lights and brake lights. 3. Temporarily remove the vehicle's negative battery cable from the battery. 4. Using wire taps, attach the input wires of the tail light converter to the corresponding vehicle harness wires identified in step 2 as indicated.
Converter Brown Wire: Tail Light Circuit Converter Yellow Wire: Left Turn Circuit Converter Red Wire: Brake Light Circuit Converter Green Wire: Right Turn Circuit
5. Locate a suitable mounting location for the ground eyelet on the vehicle near the converter on vehicle's frame or cross member.
And your ready to tow!

I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.

brown to the tail lights. yellow to left turn signal. green to right turn signal. this is a basic 3 wire hook-up i use all the time w/4wire connectors for all trailers. white wire is not used. ground is established when you hook to the ball.
to find the correct wire to splice to, use a testor (has a clip to the bare wire, and a sharp point to the truck frame). using a needle, push it through a wire to rear light harness. turn on the turn signal. check if the connection is the blinker, testing until you have the blinker wire. the tail lights can be attached to the license plate wire. brakes and blinkers use same wire, so brake lights will work whenever the turn signal is attached.
to be sure everything is working right, have a second person go inside the truck and work the signals, brakes and lights one at a time while you are at the back of the trailer telling what to do.
