Title: Diagram for firewall connector?
Post by: ken4444 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!
