Power to 7 way plug on Chevy 4500?
2015 Forester on a Chevy 4500 chassis. My 7 way plug works for lights without any problem. But, I want to hook up a signal repeater for a TPMS on the rear of the coach and I'm looking for a switched 12v power source. (I'm the first to admit I'm too lazy to run a new wire from front to back particularly when there's 2 unused wires sitting there.)
It looks like the black and yellow wires, the auxiliary circuit and brake power circuit wires, are not powered up at the connection under the back bumper. I looked under the driver's seat at the fuse block and it looks like there's a fuse in place for the auxiliary circuit (fuse#26), but there's no power to it. I've been researching and it looks like there needs to be a connection made under the dash or under the hood but for the life of me I can't find the other end of the black or yellow wires up front.
Anyone else done this that can give me a hint as to where I can find the front end of those wires? If you used them, where did you attach them for power?
