L76 swap issues

DTCs P0107, P0118, P0122, P0223 can't be cleared. Seems that the ECM is not supplying 5V to the TPS, MAP and ECT sensors. Throttle is not active.

L76, 6L80E, BCM, shifter, pedal supposedly all came from the same G8 donor. I have a G8 dash/cluster wired in as well. VATS patch applied, full flashed. All installed in a 1969 Camaro.

Got it fired up. No DTCs now.

It was the X2 connector on the ECM. 3 of the 4 tabs that are required for the harness connector to suck down tight are broken off.

Good to know, thanks.
