I have than 4 wire plug that will fit into the plug of the trailer, all I need to know is how to connect the break lights from truck to this wiring plug. it has four colors, black white green yellow. When I look at the wires running to the break lights on the truck I see green/yellow black/red then a very faded one which could have been red maybe then one that is all deffinatly black. I did try to clean the wires to see them better. I know I should take 2 wires per break light and connect each set of two to the plug. I know I have to shave off the insulation off of the proper wires to get the extra wire to run to the plug making a 3 way T. What I wana know is how do I figure out which wires to run? Some one today will get the best answer from me, I just need a thorough answer.

Hook a voltmeter to the vehicle wires one by one and turn the vehicle lights on, push brake pedal etc to exercise each wire and see what function it performs. Maybe a brown wire will be the tail lights that come on when you turn the headlights on and maybe a red wire is left turn and a yellow wire is right turn signal etc. Of course black is ground and green at the trailer may be ground also. Here's a selection of adapter wiring that comes with instructions:

The black wire is the ground wire. Some people cut corners and depend on the hitch ball to act as the ground. Wire all of them into the harness and put a cap screw into the truck frame near the harness as the ground.

Not definite in this mannequin however fuse may also be below hood or within cab. If you've gotten a seperate amber flip sign from brakes, then you've gotten a 3 cord process. Most trailers (no longer RV's) run on two cord 4 flat plug. You desire a plug that has an adapter. Go to U-Haul, they'll seem up auto and promote you an adapter at well rate. Or they may be able to set up for you. You desire a gentle tester to get each and every cord proper (only some greenbacks at automobile retailer) and anybody to push brakes, flip sign, and so on so you'll be able to discover cord that lighting fixtures up. I am a UHaul GM.

Depending on the make of your truck, I go to your local auto parts store and buy a pre wired trailer connector. There is a connector in the rear wiring harness that these connectors connect to. No cut wires and they are idiot proof. The cost is a little more than the type you have to splice, but they are well worth it.

Edge and Alk are correct. Get the proper adaptor and avoid future problems you will have by cutting into the original harness, ie: corroding connections and loss of the truck lamps.

AN AUTO PARTS STORE WILL SELL YOU AN ADAPTOR TO COMPLETE YOUR WIRING. THEY COME WITH WIRING DIAGRAMS AND COLOR CODED WIRES.
