Well.. I have been Befuddled for a while.. Trying to figure out how to wire the Alternator charge indicator light. Most will just bypass the indicator light but I have the extra spot on the dash, want to try and utilize everything that was stock in 64 and 1988.. I did numerous searches here on mud. Some sort of explained what I was looking for, most said it's not needed to hook up the alternator.. While i know it is not needed to hook up the alternator it's something i wanted to hook up. SO.. Long story short I found this PDF which might help others diagnose their alternators. It's a toyota training manual..
And now i know to hook the power side of the charge indicator light to the ignition hot wire "IG" that tells the alternator to charge and ground the charge indicator light to the "L".
WHOO HOO for me.. This means that the Drivers side of the whole harness will be complete and I can start looming it.
THought i'd share a bit of info I have never seen before and answered my question.
