Re: 72 Sierra Grande wiring - still at it

The picture is of wiring on the engine side of the firewall to the right of the distributor. There you see a cut off 12 gauge red wire. What would that be for?

I checked all the fuses in all ignition switch positions, using a neat reference on the forum. Everything checks out as it should, power is feeding the right things except for the ignition circuit.

Not sure on the Blue wire then. I downloaded your picture and added some arrows. The single and double arrows indicate what I think is the adapter for the camper tail light wiring. If that is what it is you can actually remove it and plug the original tail light wire connector into the firewall plug. That may get rid of some of the extra wires in that area.
