After reading multiple threads about this I just wanna see if I can clarify this, should the TCM data wires(38,37) be spliced directly into the connector at B&L? I also read in one thread about splicing the TCM into the ECM wires and then running it to the DLC?

I'm currently getting a read error on my scan tool but I ran out of daylight before verifying I didnt mess up the the data wires at the connector, but wanted to see if someone could clarify either way.

 

I figured it out for anyone who may have a similar problem later.
This is a more accurate diagram of what I had going on and I had the TCM wires going into the splice saver to the A&M slots, because I read it as the TCM going to BCM then into the splice. Instead the ECM/TCM wires splice together then run directly into the DLC. Maybe this was obvious and I just read into it too much, but I also had the full splice saver from my donor. Either way there ya go!
