The original 350 engine for a 1982 GMC C3500 was rated at 165 HP. The Mexican built crate engine I took out was supposedly built for 250 HP but I doubt it was making that with the 1982 2V carb,...

I got a dual brake switch from a Camaro. Connect the purple wire to +12V through the normally closed contacts on the brake switch and that's all that's needed for that?

Does the TCC work when the...

I took out the diode box for the RWAL, no ABS on a 1982 truck. But what do I do with the purple wire to the transmission?

I got the cluster out of the 91. It has oil pressure, amp and temp gauges.

Looks different. The 91 connector is pretty similar to the 82 connector, has a "claw" on one side to hold other plugs but there are more contacts in the 91's connector.

Much farther south. Weiser. I can see Oregon from my house. :)

Those may help. Thanks.

Looking more and more like I should just cut the bleeping thing off at the inside of the ECM bulkhead plug and start from there. I went to a GM dealer's service department...

1991 two wheel drive C3500. 350 V8, 700R4. It had air conditioning but did not have cruise control.

I'm planning on upgrading the gauge cluster from the simple idiot light one it has to the one...

I'm doing a project, 1991 350 TBI and 700R4 into a 1982 GMC one ton dually flatbed. Much "fun" figuring out the wiring. Sooo simple in 1982 with no emissions equipment at all, not even EGR.

I'm looking for engine compartment harness diagrams for 1991 Chevy and GMC C/K truck, with the bulkhead connector and circuit number list.
