I have two used 8041 PCM's $60 each Shipped in CONUS, buy both for $100 shipped


I have one NEW LT1 8051 PCM - $100 shipped


I have rebuilt Optispark harnesses. All of them have new Optispark connectors and pins. I pushed the connectors out of the busted connector bodies, cut off the terminals, installed the new connector, and installed new terminals. These connectors are "Pull to seat" style, so this is the required process to change the connector without having splices in the wires. The other end (grey connector) is untouched. $45 Each shipped in the US. These harnesses are $110 new from GM.

I also have some NEW harnesses I made a few years ago. They are made with new connectors, terminals and GXL wire (OEM is thinner jacket/insulation TXL). Those are $55 shipped.
