Default LS1 alternator connector wiring question.

Ok I know I need to wire the "L" terminal of the 4 wire alternator connector up to the dash dummy light. BUT... The connector I got new from GM is labeled from drivers side to passengers A B C D.

My question is which terminal is the "L" terminal.

Many thanks in advance.

S F L P. S is the 10 ga.?(largest) wire that goes to ignition then the F(field) then L which is the one for the light circuit. Sometimes the alternator is marked on the regulator.

OK so "L" is the third one over from the drivers side?

Dude, just look at the connector pic in the lower RH corner and compare it to yours. It's not rocket science, the connector only fits one way.
