Posted in an existing thread in the gen 4 section but they weren't much help. I am building a 02 lq4 with LSA heads and a ls3 intake and was wondering if the 12592525 3 bar sensor off the LS9 would be a plug and play (with the correct harness) using the custom 3 bar SD OS on a 02 silverado pcm. Or does anyone know where i could find out?
