Thank you. Great reply!

For reference here is your excellent list:

(1) The engine harness (that you purchased)
(2) The alternator / headlight harness
(3) The cab / under-dash harness

I wasn’t even aware that the Forward Lamp Harness (2) might be different but I now see, from your suggestion and my catalog, that it must be. Those are spendy by themselves at $95. Add to that the Engine Harness (1) at $80 and then there is the Dash Harness (3) which is $280. That’s $455! (if my quick math is good)

Let me jump to the question…..

Can someone give me a quick wire diagram for the Engine Harness w/ gauges and HEI? If so I will create something to get me by and when it comes time to rewire the whole truck I will make that decision at that time.

Thank you.
