I can't find a wire in the engine bay to supply keyed run & start 12v power for an HEI distributor. I can run it off of the Alt. but then have to disconnect to kill the engine.

Yes, this car's been "Americanized" (GM 350/350) and I'm trying to get it drivable to better determine it's future. PO said it had an engine fire but it looks like the wiring isn't too bad.

Questions:
#1 All of the wiring, even under dash is tape wrapped; could that be original?

#2 I can't find a color coded wiring diagram that I can read. Anyone here have one for this year to share?

Thanks

 

On the passenger side fenterwell there us the starter relay, I'd check there.

But hey since you have a 350, you could swap in a t5 or tko and have a much more fun car to drive (:

 

I don't have a '76 diagram in front of me but the Jags back then were pretty consistant in wiring colors code.

Solid white wires are usually "key on" 12v

Solid brown wires are 12v constant

White/yellow at the starter relay is 12v from the switch in "start"

White/red from the starter relay goes to the starter solenoid to engage the starter

My older Jags had taped harnesses under the dash. In the engine bay some harnesses were tape wrapped and others were cloth covered

Heyyyy, good idea, I didn't think of that. A possibility, I already have a T5 stashed away to rebuild for a past project. Hmmmm.

 

Big wish on the relay, only thing left on the pass. fender-well is a fluid bottle. But thanks for the color coding, I might be able to find something behind the glove box, I saw a few cut wires back there.
Thanks.
