1981 P32 Chassis Wiring Diagram

[uptickguru]

Hi All,

Looking for a Chevy P32 Wiring Diagram. I am rebuilding an 81 Foretravel with a 454 Engine. Also, any diagrams of the air suspension system.

Thanks for any help

Cheers!

The wiring then was very basic and common across GM’s light trucks. Any Chilton’s or similar manual will work for that, suspension, most of the chassis.

Our group (GMC Motorhomes International) has a lot of information filed just for reference, and I thought one of them was a wiring diagram for the P30. I will keep looking. Frank

All of those but brakes go through the light switch. GM did a really good job of over loading their light switches. Have you checked that out?

Copy that and put an "H" before the address when you paste it in the address block. If I paste it complete here it links to a portion of a large image.

I agree on the light switch. They added way too much load. I replaced mine and added a couple new relays to handle the loads.
