I\'m in the process of finalising the wiring for my FC EGI engine swap in my Mx5, and I\'ve come across a wiring problem I could do with a little help with!
The mx5 and rx7 alternators both have 3 connections, one main thick wire that bolts down to the alternator, that carriers the power away, and a pair of smaller wires that are only signal level.
With a combination of wiring diagrams and testing I know which of the two smaller wires feeds the charging warning light in the dash on the mx5 side of the loom, but I\'m struggling with the rx7 alternator side.
I have a workshop manual downloaded off the internet, but the wiring diagram is probably one of the worst I\'ve dealt with! I\'m struggling to make heads or tails of it with the alternator issue.
Can any one tell me which of the two pins on the rear of the alternator feed the charging warning light in the dash please?
