With a GMPP E67 LS7 (2008) there is , of coarse, no cruise.

The instructions tell you to treat the system as an 06 CTSV, wiring and diagnosis wise.
The CTSV cruise is all intermixed with the brakes and traction control so I don't see that as a possibility.

What I do see is the 07 TBSS cruise wiring going directly to the E67.
Would this be do able with no BCM , modding a TBSS flash ?

I see many AU based aftermarket kits for specific fly by wire kits.
Has anyone made anything compatible to the E67?

Thanks for any input.
