I did this very same thing last year for a friend. played with settings in hptuner, and even though i got it to correctly recognize the shifter in S mode, TU/TD still would not work. took the same computer, programmed it like a 2009 Corvette, and it started working right off the bat. in the truck, these things go through the BCM.
Eithere wire and use the BCM, or switch to a corvette OS. I can give you a hand if you need, PM me.

An 09' has a different ecm than a 2014 pickup, does that matter with the OS?

Hi
I could have use for 2013 Camaro SS 6L80E schematics... And also for that L99 and LS3 engine schematics...
I bought complete engine/trans pullout from '13 Camaro. I have gas pedal, ECM that controls also trans.
Now that L99 engine is converted to LS3 and several wires are useless... We have to modify that original harness... I also did a new thread for that but if this message reaches you and you could help me... That would relieve my headache..
Keeping my thumbs up
I have had several sleepless nights because of this.....

Hi again.. I'm making progress but can someone help me with those two pairs of wires that comes from gearbox... Those are "computer data lines system" and I don't know what to do with those... I assume that in Camaro '13 those pairs goes to Body Control Module, but I don't have that in my oldie...
Are those just GMLAN high wires and in my situation, could I just end them or what?

GENIIIDude,
Were you able to confirm if the TCC brake apply wire goes directly to the TCM or if that is communicated through the CAN BUS? I traced the blue/white wire from the ECU to the brake switch and the BCM going to the tail lights, but I cant find anything tracing it back to the TCM connector.
12SEC SS,
Can you PDF the TCM wiring drawing and PCM pinout for a 2012 Tahoe 5.3 & 6l80?
