12581565 pcm? Sorry for the newb question. Looking forward to updating the electronics on a thirdgen TPI and collecting parts, a 2003 Silverado came into the local wreckers with a 12581565 pcm- I was going to grab the harness, coils, everything- question is- 411 vs 565, same thing or avoid? I'm thinking the harness and is fine even if I have to source a 411 else where.
