Can anyone tell me exactly how to pull the codes off of an 88 80q ? I made a test lamp by soldering a 330ohm 1/2 watt resistor on the "+" side of an led, and then soldered a wire lead to the "-" side. I put a solid jumper wire in each side of the relay labelled "Relay for manifold preheater, K- Jettronic". It was the only one with connectors on the top of it. Please Help TIA River6822@aol.com 88 80q
