E38 pinout discrepency between Vette and Truck? I noticed today that the "starter enable relay control" pinout for the vette is pin 67, versus 52 for the trucks. This is according to Mitchell ProDemand. Can i assume that if im using an 07 Vette OS to control an ly6/6l90 combo that i have to repin the harness to match the vette wiring?
FYI this is in a k5 blazer that was swapped by someone else, so im not even 100% positive how its even wired in the first place. General consensus is that they mismatched early and late OS's and locked me out of the ECM. I ordered a new ECM with an 07 Vette OS in the hopes of getting TUTD functionality.
Big thanks to anyone that takes the time to put in their .02

What PCM does the 07 vette use? I cant seem to find if it is a e38 or e67. When I pulled up diagrams for the 08 trucks and vette they all used pin 52 same with the 07 trucks. The 2007 vette seems to use pin 67 but I`m also finding mixed posts saying that some or all of the 2007 vettes use the e67 ECM.

According to everything I've seen, it uses the e38. I spoke with the company we purchased the ecm from, explained what i was trying to accomplish, and ordered an e38 for an 07 Vette base model with an LS2 and 6L80e.
