Last night I decided I was going to do the fast idle mod to my truck. Found the pto wire but no upfitter wires. Pulled the switch panel and nothing is plugged in. Looked for the relays and where they are supposed to be is nothing but a lot of air. Anybody got just the harness and relays from a wrecked truck that they want to part with?
I had trouble finding mine when I did it. I kept looking under dash around the steering column. I found the upfitter switch wires up above the parking brake. I about went crazy for a while trying to find these.
i think he is saying that he pulled the upfitter switch panel out and there was nothing connected to the switches themselves... not that he couldn't fined the capped wires....
yep. no sign of the harness anywhere. no plug behind the switches, no wires near the obd2 port, no relays above the glovebox.
