yea i didnt know i would need the old harness to have power in the cab have the motor running jus no power in the cab i have to jump the solenoid to start ittho
If you gave him only the engine harness, you are OK as that is separate. There's a wire w/ a fuse link near where the starter solenoid is/was that needs to be on the batt side of the starter solenoid. Once that is connected, then you will have power to your cab. This wiring is separate from the engine related main harness.
If this was removed, will have to get one from a j/y, get it back from that guy cause he don't need it, or get an EVTM and just wire it up yourself.
Edit, if you had an auto (not sure about manual) you neurtal safety switch will cause a no start since part of the circuit DOES run in the engine main harness. I subtracted this circuit from my mainharness so that I could retain the plugs. oil pressure, temp, etc all run through those dash plugs also, gave a way an important piece IMO, but not a deal breaker..
