OK I just picked up all the TPI hardware. The ECU turned out to be a 165 unit but the guy I bought it from swears it came out of a 1985 Camaro. Is it possible that the 165 was used toward the end of the year? The harness is a complete stock harness, so I have a lot of ringing to do to identify all the plugs and non-essential portions of the harness. Charles Brooks
