Question:

Will splicing the brake and running lights together for trailer lights cause any problems for a vehicle?

The trailer light cord has 4 wires, and my colorado truck has a separte wire for both brake and running, so can I just connect the tail wire from the trailer plug to both of them?

Answer:

pretty much a easy job just do it right use the right tools and you should have any worries heres kind of what you have to do
make beneficial that the working lights have a sturdy floor. attempt each and each gentle with a 12volt stick gentle tester and notice in case you have capability coming to each and each gentle. additionally examine continuity on the brown twine to make beneficial that's not broken some the place. Do you have a 4 lead twine set or six. If six leads: Blue is for backup lights, and crimson is for electric brakes on trailer. examine source from the place the capability is plugged into trailer harness and notice whether it is warm interior the plug. if so, floor fault some place.
DO NOT wire the running lamp and brake lights together. It will blow one or both fuses and make the lights work improperly. Your trailer also has separate running lights and brake lights. One wire on the trailer plug is for ground. One wire is for running lamps. One wire is for left brake/turn signal lamp. Last wire is for right brake/turn signal lamp. Have someone whom you know that is good with car electrical wiring wire this up for you. Other wise yes the truck can handle the trailer lighting system just fine. P.S. You do need an adapter that you can buy from your local auto parts store. Match up the one that will fit the trailer plug and then follow its instructions to wire it up. If your trailer does not have a plug that connects to the truck then buy kit that will have both plugs (one for the trailer and one for the truck that connect together) and follow the instructions to wiring them up.
I have had plugs come out on me after a few thousand miles, I would get the tire patched properly.
i had tires plugged before and i ran the tire out. it was still holding when the tire wore out.
