You need to verify which relucter came in the GTOs, the 05 corvette motors were the 24t relucters and the 06+ had the 58t relucters. For some reason I seem to remember all GTOs had the 24t relucters but I could be wrong, that's why I say verify the relucter because other than that they are the same.

no corvette came with an ls6 in 05.. only engine you could get was the ls2.. so its an 04 ls1/ls6 harness or an 05 ls2 harness..

Didnt even notice that, like matt said only LS2 in 05 (which is what I was refering to as being compatiable). If its a LS6 harness it can be made to work with extending a few wires and changing the injector plugs, but it still comes down to the relucter.

All GTOs were 24x.

OP, get a pic of the ecm. The ls2 looks very different than the ls1/6.
