Looking for wiring for a 74 with original wiring to alternator. Yes I have the schematics but still need help.
The schematics shows one three block of connections.
Looking from the back of the alternator froward.
At 12 o'clock you have one small spade and two larger spades(both are for the battery and have 10-12 gauge wire).
What colored wire goes to the top smaller spade?
Then at the 3 o'clock you have another smaller spade.

Both of the smaller spades are my concerns.
Is the top one suppose to be the brown/yellow wire or the smaller brown wire.
Then which ever one left goes to the 3 o'clock spade. Correct?
Is there anything I left out?
If on the car the 3 spades are 3 o'clock and the one single is at 6 o'clock.

From MOSS tech support- Only need 2 wires connected to make work.
The larger spade needs the larger brown wire that goes to battery and the brown/yellow (ind lead-that controls the red light on dash) to the smaller spade.
