Ok so I have finally gotten around to putting a 4l60 into my ls swapped c10. After getting it all hooked up I am getting two codes. P0740 and p0785 I have checked the 2 pink wires at the trans connector and both are getting power. The trans is a freshly built unit. My problem is I have no 1 or 4 gear only 2 and 3 and no lockup. I have a relay setup an working for the converter lockup. The one question I have is where do I hook up the off/run/crank wire coming from the PCM? Do I go hot all the time, hot with key on, hot with engine running? I am very confused on this and cannot locate the answer. Also any insight to a potential fix for my code problem is much appreciated!

i found the problem. Ended up the harness was missing a few wires, and the trans connector pinout was incorrect. I guess i got some sort of bastard harness. I modified an 05 1500 harness to standalone.. works great now
