My Truck - 1965 Chevrolet C10
later model sbc v8/with factory gauges

I have the 1963 Chevy Truck shop manual and the 1965 Supplement for reference.


Howdy folks.

so, I am trying to swap to a internally regulated alternator on my 1965 Chevrolet C10 pickup.

It has a later model v8 and factory gauges. <- This gauges bit makes a difference in wiring harness land.

Also, I have no idea if my truck was a v8 originally or not, so many things were changed and swapped before I bought it.


This is the harness I have procured:

Front Light Harness — Altpi

PART #: 04715PI

FRONT LIGHT HARNESS — ALTPI, CHEVY PICKUP, with factory gauges

Note: Modified for passenger side 1983-85 and earlier “SI” series internal regulator alternator


I am trying to sort out which wires go where. Photos on the link below:

According to my 1965 Shop manual supplement(body and chassis electrical 12-6) the dark green wire with the flat black connector goes to the horn. My horn(s) are just wired straight to a dark green wire, so I guess that is where it goes.


Here is my thinking, which may be wrong, hence why I am here! headscratch

I think the big thick red single wire goes on the top connector of the horn relay, where the wire comes across the front of the truck from the battery.

The big wire with the smaller black & white wire goes on the bottom connector of the horn relay… I *think*.

However, I'm not sure... so, here I am.

Thanks folks!
