Because the EZ-TCU shares a tach signal and tps signal with the EZ-EFI system, to facilitate wiring them up together, I needed to remove the old TCI transmission control unit and wiring harness. I have the tcu mounted in the stock center console, and the harness routed through a hole in the floor. I removed the old tcu, then the console, and then pushed the old harness through the hole and disconnected it from the 4L80e tranny. Here's a couple of pics of the old tcu and old harness connected to the tranny.

Because I am such a stickler on hiding wiring and trying to make everything appear as factory as possible, these pics are over several weekends of work. My buddies are calling it SLOW EZ-EFI because I'm taking so long to get it finished, LOL.
Anyway, 98% of the wiring is finished, and I just have a few loose ends to wire up in the cab...mostly the new TCU, and then it will be time to fire it up.
Hopefully in the next couple of days with a little effort after I get home from work. I will keep ya posted.
