700r4 wiring with an LQ4 6.0 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all, swapping out the TH350 in my 72K10 for a 700R4 that has been rebuilt. Main reason is to get the engine 2" forward without changing transfer case position or driveshaft lengths, and the overdrive. I already have this tranny, know it's not the best for this application but it's been built heavy duty..
So my question is can I use the stock ECM to generate the lockup for the torque convertor? 700R4 has 3 wire plug. I modified my own harness if that matters..Thanks
