I would say the easiest thing for you to do would to be to trace the wire from the tranny and either tap into it there or follow it up into the wiring harness up above the drivers side fender well. I believe the one you want is in the bottom right block out of the 4 wiring blocks there..someone may come and correct me on that but I belive they are labeled 12

I tapped into it at the forward most block, of the 4 blocks on the driver's side inner fender. I can't remember which pin it was though.

I tapped into the plug that goes into the top of the trans pass side. Pull the connector, it's hard to reach with the exhaust in the way, tap into the purple w/ yellow trace. That way you are sure to have the correct wire, because it's possible that it may be different color at the other locations as you reach the cab.

Hope this helps. Good luck

It's pin #6 on the block that Jeremy refers to.

As stated above, But my comment, There are 4 connectors under you air cleaner box. The forward one is grey. I unplugged that one and let it drop out the bottom. Crawled under and pulled out the red tab and slipped out #6 (Purple with yellow trace) Tapped it up and plugged the grey connector back in. Went for a drive to make sure i have the right wire. Yup, That was it and the wire i used. With that pulled out of the connector the tranny shifted hard due to the wire being disconnected. But the TC didn't lock which was my test.
