Engine Harness Question
 

I'm sure this will seem painfully obvious to someone (at least I'm hoping it will)...

Last September I pulled my 283 (with pertronix distributor / coil) because the old small mouse was TIRED - life happened - now I'm trying to finish up a "simple" 350 (OEM HEI) install nearly a year later (life).

The picture is my engine harness (from Classic Parts) that worked fine for the first install but I (am simple and) have lost all recollection of the green wire's purpose - I think it would have been for + coil for the old points set up before the conversion (and I think I still connected it after Pertronix Conversion)

So can someone just have mercy and help me verify and remember before I make a mistake?

Thank you for your consideration.

Stay well and blessed.

From what I recall Green is Temp, blue was oil. :uhmk:
Maybe pink is coil and white is coil?

Wait I found a wire harness thread, post #8 is OEM - http://67-72chevytrucks.com/vboard/s...d.php?t=378484

maybe I am wrong, but I just went and looked at my AAW setup and white is tach, pink is batt on the HEI distributor and green is temp sensor.

The thing about the OEM wires and the HEI is that those little wires simply aren't cut out for powering the HEI. I use a 10 gauge wire from one of the ignition hot spades on my fuse block for mine. Some say splice an inline fuse on the wire, others say don't. Personally I don't. As for the OEM wires you're looking for one that lights a test light when the key is on. Guage sender wires wont do that.
