New build BCM questions.

[mljr]

I'm in the process of swapping a 6.2, 6l80, and np263 into an '85 k10. Im already aware that in order to get my TCCM to function properly I'll need a matching BCM to my PCM and TCCM. Once/if those are acquired what connections does the BCM need to make my TCCM funtion and shift properly.

Who told you that?
Only reason is VATS. You disable that in the tune.
