Please use this...... Also, something to keep in mind. I had a truck that had a short in the AFES mod which caused the truck to lock in 2nd. We were getting no power to the TCM. If memory serves me right, wire 2 off of the transmission relay is where the mod is plugged in to. I believe it is wire 29 tango. If you are having problems with tranny that is locked in 2nd and you are getting no power to your TCM try unplugging the mod and hooking it back up the old way. Worth a shot.

wiring diagram help... highlight the wires you are tracing, 3 colors power, ground and power after a switch or control command function. this makes the "big picture" a little smaller and gets rid of the unwanted info
