If you adding a trailer light harness, you can buy a seperate harness from most auto parts stores that will plug right in. There should be a connector near the rear of the truck that you can unplug, and add the trailer harness. It's simple and fast and you don't end up making a mess of your wiring. I suggest puting some "dielectric grease" on the connections to prevent corrosion.
Flat 4 connector.
Brown is tail lights and marker lights.
Yellow and Green are turn and stop. I think yellow is left.
White is ground.

1999 dodge ram 2500 turbo diesel the trailer brakes won't work and I tried a different truck to make it was not the trailer any ideas?

We just had the same problem with our 99 2500 Turbo Diesel Ram. The problem ended up being the factory trailer cord recepticle near the hitch. When we unplugged the harness from the back side of the recepticle we found that the brake terminals had gotten hot and burned out. We replaced the recepticle (about $30 from Dodge) and our problem was solved.

Want to tap 4 pin conn on to my thuck trailer harness that has a 7 pin. what colors from 4 pin to colors on truck?

don't tap into any wires,as moisture can then corrode wiring and you will have big problems later,check with companies that specialize in connector adapters that do the same thing you need to do,but with their set-up you can always just unplug their harness and revert back to the original set-up you had w/o splicing check with a auto parts store
