First. Badass. Cant wait to see it with the big boy on it.
Second. Tell me more about this ARB wiring harness. I presume that there are wires coming from the ARB bumper that you were supposed to be able to piggy back off of the factory socket harness behind the tail lights.
Is it a matter of the sockets wont plug in, the wiring is not coded correct, etc? Can you take pics of the wiring?
I presume that you want the ARB bumper to have redundancy with the factory lights?
Anyhow, here is the tow harness, I bet we could get the ARB harness to work though once we know what we are looking at.
