Goin to pickup a 2004 GTO M12 T56 tomorrow morning from a local salvage yard. 11k miles, 6 month warranty, no core charge, and they have a carfax report on the GTO as well. Also was told that they do not cut the wiring harness, so maybe I can get one from them as well. Will post pics, hopefully over the weekend.

Thanx for all the info. The speartech harness is expensive, sure looks good though.
