Re: (CivicSpoon)

I remember hearing or reading something about this method but i am unsure;
the obd1 harness has 4 wires going to the alternator plug.
the obd2 alternator has 3 wires.
two colours are the same from obd1 to obd2 obviously the other 2 are not.
can i somehow convert my obd2 to a 3 wire alternator by eliminating the connecting plug.
Any help is greatly appreciated
