Thanks everyone for your input and ideas. I think I can figure out now how to wire up some lights with your wiring diagram klhansen.Mine are cheapo fog lights that I built a bracket for to mount them alongside the trailer hitch.
I wired them to a double throw switch so they would either work with the backup lights or independently.

My old setup did have a relay in it because the lights were probably halogen...I don't remember for sure. But I know I need something besides the stock back up lights because they don't do much for me.I picked up a LED three or four inch round model from NAPA.I mounted it on under side of hitch.It puts a ton of light out but does not pull a lot of amps so I was able to just solder it to the revers lights wire.I plow at night and they are worth their weight in gold
96Cobra...Do you remember where you got the LED replacement lights and the P/N? They would be worth a try.Something else to think about, depending on how much extra light you want, you can buy upgraded LED replacement lamps to replace the stock back-up lamps. I'll try to find a pic I took halfway through my install...
