Question:

Hi I ordered a 55372 harness for a 2002 ZR2 Tracker, I found the 6 pin lug and plugged in harness. I only get marker lights, no brakes, or signal lights. I am using this a flat towed vehicle behind RV Thanks

The problem you are having is because the Curt 4-way kit part # C55372 is not for flat towing and is instead for towing a trailer which basically works in the opposite direction as what you are wanting. This kit is designed to control the taillights of a trailer connected to the vehicle whereas tow bar wiring is designed for receiving voltage instead of sending it.

We don't have anything custom fit for your vehicle but the diode kits will work well.

For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.
