I’m working on my 71C10 swap, 2010 6.2 Escalade L94 harness with E38 and 6l80e. I already removed everything I don’t need to fire it up. I have a question on a blue wire and orange black wire going to 6l80e from ECM. Blue is a serial data that isT’d off and heads to the BCM and a orange/black that is a replicated TOSS from ECM to TCM, are those needed? Thanks, any help would be appreciated
