Cooltech help?

[psw757]

Our rv has a 7 way hookup and my blue ox umbilical is the 7 to 6 wire type. I am going to use a 6 connector on my rubicon bumper rather than the 4 type cool tech supplies with the harness. Should I still follow the mapping that cooltech supplies or should I follow the mapping on the husky towing 6 trailer plug? I'm kind of confused with this. I have the whole thing installed, just need to connect the bumper plug the right way.

Well.. Try this. DO NOT HOOK THE GROUND WIRE up at first. (Nor mount the "Trailer" end connector on the towed)

Hook it up, Either ground via the hitch or use a standard Jumper cable, frame or negative battery post on towed to frame on RV for ground, and then test the lights and brakes.

if everything works as it should.. Hook up the ground wire.

NOTE: If you have a battery wire, Do not hook it up either. Use a volt meter to measure the voltage on that lead with the Motor HOme engine running.

Normal alternator voltage on the line, go ahead and hook it up, ZERO, check what you THINK is the ground lead.

That is basically how I wired every trailer I ever had, Hook it up and see if it works.

Actually being a high tek kind of guy, I metered each lead, then applied power to the proper trailer lead, verified I had the right wire, and then hooked it up got it right every time that way.
