What the heck is that wiring harness for ? (Body)

Hey,

a short question from Bavaria

I have 3 of these focking harnesses:

This harness has not been connected to anything on all of the three K5s and Jimmys I owned. It is quite a heavy wire that runs from the engine bay to the rear. Harness each were cut and taped on the end....

??? Some kind of trailer power supply ???

Looks like the wireing for trailer brakes.

Thunder nailed it, it is electric trailer brake controller wiring.

Hey,

thanks a lot! I'm not gonna put this harness back into the truck ;-)

All the Suburbans that I have owned have had that. I always thought it is a good, high quality power source to use for any 12v needs at the rear of the vehicle. You can use it w/ a relay for good rear lights etc.
