So I finally got aroud to putting in the CDL today and everything seemed to go well except the PIN 7 mod. For those of you who don't know...here's the instructions per C-Dan.
Remove the dead pedal and the left front sill plate. In the left kick panel you will find a Silver metal box. That is the ABS ECU. Remove it, and behind you will find a black plastic relay about the size of a cigarette pack. It says "transmission control relay" on it. That's what you are after. The EWD calls it the "center diff lock relay", same thing. Unplug the harness from it and take a terminal pick and remove the black wire with blue tracer from pin#7. Insulate the bare terminal to suit and then put everything else back where you found it.
Thought I followed this to the letter, but once everything was back together again, the CDL locks, but doesn't unlock. I tested it before the PIN 7 mod, and it seemed to work then, but everything is buttoned back up now and it's not unlocking. I did notice that there were two wires that I could have pulled in the final step. See teh picture below. There was a thinner black wire with blue tracers, and there was also a thicker blue wire with black tracers. I chose the first option, but don't know if I did right. Anyone with experience?
