Diagram for firewall connector?
« on: May 17, 2018, 06:44:24 pm »
Does anyone have a diagram that shows what each terminal on the firewall connector is used for?  I need to find the gas tank sender wire on this:

I'm also going to assume it's the 88 suburban wiring harness?

thanks very much!  I apologize for leaving out the model and year :)

Yes, I believe this is an '88 suburban wiring harness, and I assume that includes the bulkhead connector!

I’m looking for the same diagram as the original poster for a 1979 Chevrolet C 10 no AC gasoline two tanks as it looks like somebody cut some wires underneath the hood and I’m trying to fix my accessory wires and constant 12 V wires any diagrams, numbering labeling on pin outs would be highly appreciated
