I purchased a lovely new engine harness (setup for HEI) for my '69 El Camino. My car is an idiot light car, much like it's owner...
I'm an idiot because I removed the old harness without marking where things went. While the new harness is color-coded, I'm having a little bit of trouble deciphering where things actually go.
The AIM has some info, but it's black and white and doesn't seem complete to my untrained eye. Here is what the AIM shows:
- Starter motor (two wires plus battery cable)
- Blower motor (one plug)
- Wiper motor (three plugs?)
- Oil pressure switch (one plug)
Here is what I can see on the harness itself:
- Two-wire plug (pink & yellow)
- Single-wire plug (light blue)
- Two-wire plug (dk. blue & yellow), which is linked to...
- ...a three-wire plug (2x yellow, black)
- Single-wire plug (dk. blue)
- Two single-wire ring terminals (yellow & purple)
- Single-wire plug (orange)
I think one of the single-wire plugs (the orange one) is for the brake light switch. I think two of the two-wire plugs (presumably the linked ones) is for the wiper motor -- I have non-hidden wipers. I think the two single-wire ring terminals are for the starter motor, though I don't know which are which.
So that leaves me with the oil pressure switch (which has to be a one-terminal plug) and to figure out how to wire the distributor -- I'm running a HEI distributor from a '79 Camaro.
What about the alternator? I'm using a 10Si alternator, which is now internally-regulated.
I also have a new forward lamp harness to go on too, but that's for another day
