do anybody know how to convert the wiring to put a OBD-2 Alt. on a OBD-1 wiring harness ? i have the alternator plug but i dont know where the 4 wires goes to ??
i try to find wiring chart or something but nothing !!
thx

 

i believe obd2 alts use 4 wires and obd1 use 3 wires. if u search for ECU pinouts or something along those lines u will find a chart that lists all the wires and what they are called and all u do is connect the same named wires to each other
