TH400 to 700R4 swap - lock up wiring
« on: June 07, 2015, 07:07:22 pm »
I just swapped my TH400 for a 700R4.  I have EBL Flash and I want to control lockup from the computer.  I have the 3-wire connector that goes into the new transmission.  My question is what's the best way/place to find the wires in the wiring harness to connect the connector and operate lock up using the computer?

The 700 in my old truck didn't have any computer at all

Thanks for the suggestions.  I wired up a manual switch for now, but it's popping fuses.  Maybe these links will help me figure out my next option.  Looks like more troubleshooting this weekend
