~ Has anyone ever had to remove a pin and replace it from the bulkhead harness? Is there a trick to release the pin? A paperclip or two perhaps? The pins on the engine side of the harness are spaded. One is larger than the rest. I dug out the dielectric grease....still trying to trace down the dead short in the "Gauges" circuit. With the harness connector unplugged, the short to ground on that pin at the fusebox (left spade) goes away.
~ There is a wire in the schematic (74 Vega/Monza) that shows "resistance wire" as well as the same words printed on the outer insulation of that wire...What's it for and what makes it a "resistance wire" ?
Thanks in advance

To remove the metal clip on the connectors [I have never actually tried on an H-Body but I did on my full size G-Body van and that was the same as the headlight types found on H-bodies], look down the business end of the connector and you should see a raised prong/barb that if you push the connector in a little, a jewellers screwdriver should release the tab, while still inserted gently pull the connector out and repair/replace as required.
Resistance wire was used up until 1974 on anything with points to lower the voltage/current through the points to make them last longer. By 1975 I believe GM had gone full HEI on all production vehicles, 1974 IDK for sure, I recall that as a transition year. There will be a wire from the starter solenoid to the points for start only, connected to the same terminal as your resistor wire. Hope this helps. Harry

Thanks Harry, it worked out great.

Glad to have helped out! Harry
