We are swapping an aw4 where a nv3550 use to be. We are using the write up on Stu Olson’s page and is pretty easy to follow. We are in need of a little wiring help. We are supposed to use pin 28 white (with black stripe) on the grey ecm on the Tj. That pun isn’t used so there isn’t a wire. It’s the ccd buss - . Is there anywhere else we can find that wire in the harness?
