How to Connect Prodigy P3 Wiring to a Renegade Valencia RV on Freightliner S2RV Chassis

Question:
Hello, I have the Tekonsha Prodigy P3 Trailer Brake Controller, however im looking to find the correct wiring harness for the Renegade Valencia RV on the new Freightliner S2RV chassis I know it is not the 3027-P because that one is a 4 wire and i need a 6 wire harness

Expert Reply:
The Tekonsha Plug-In Wiring Adapter # 3027-P you referenced is designed for some of the older motorhome models so it doesn't surprise me that the plug doesn't match.
With that being said, I'm not sure if you've found the correct wiring connector on your Freightliner S2RV Chassis either, since electric brake controllers only connect to 4 functions. We currently don't have a plug we know that matches your motorhome so I recommend using the universal pigtail that came with your P3 # 90195, pigtail is part # 20127 if you don't have it anymore, and splicing the wiring in to match the following functions:
Blue - 7-Way Output to Trailer
Black - 12V Power
White - Ground
Red - COLD Side of Stop Light Switch (only gets hot when brake pedal is pressed)
You'll need to verify what functions you have with a circuit tester like part # PTW2993.
