need help with gpr wire location

[u.p.cowboy]

2000 7.3 f250, I am wondering where the power wire black w/ orange stripe, on the gpr goes to, right now I have it to the always hot wire on the starter solenoid on the passenger inner fender, is this correct? I was messing with some of the wires and I cant remember where it goes any help is greatly appreciated. I know where it hooks onto the gpr, I need to know where the other end goes
