Pinout for 2007 T42 (truck/avalanche)

[Cougar281]

Yes, my harness works with LLY, E40, P11, P12, P05. "Low Reference" is the same as Ground, they are all joined in the ECM.
Your pinouts suit the LLY, but you can reconfigure them to suit the LLY and the other controllers I listed if you wire it up like the document shows.

Cheers,

Cool! Thanks Ross. Guess I'll wire up the LLY connector todo the P12, LLY & E40, and change the other one up to an E38 and maybe add a T42. Can I wire up my LS1 connector with pin 60 as ground (60 on the 98 LS1 is ground, 99+ is some kind of ground {SEN GND}) so one connector will work with 97/98 & 99+ LS1 PCMs?

Edit: I figured out the LS1... Pin 60 will work for all the LS1's. Only one I'm not sure about is the LB7. Pin 60 isn't used. Doesit happen to tie in with the grounds?

Edit2: Looks like Pin 21 will work for all the LS1's and the LB7; it's a Low Ref on the 99+LS1 and LB7, and a ground on the 98 LS1.
