Not sure if this is discussed somewhere else, if so my bad for posting again but i have a jdm h22 in my 97 sh. Kept the obd1 alternator since i didnt have an obd2. Got a plug of an obd1 harness, not sure if it was a prelude or not but it only had three wires, my harness going to the alternator has 4 wires. Anyone have the diagram to convert this? Am i gonna have to repin the 4th wire into the plug since there is an extra slot there and i do have 4 post coming out the alternator? I have tried 2 batteries with the way i had it first wired and either the batteries are shot, which one is practically new or they are holding a charge. Once i get the car jump started it stays running but once i turn it off and back on the battery has no power. Just wanna make sure i have the wires right b4 i rule out the battery.

 

got my battery check and it is just very undercharged so my alternator my not be charging cus the wires arent right or sumthin. can someone hook me up with the correct wiring??

 

your local auto-electrical/alternator/starter shop should be able to hook you up for under $50.

 

i need to know which wires go to which since my harness is obd2 and my alternator is obd1, and i got the obd1 plug but theres only 3 wires and my harness has 4.

 

guess there aint much help on this topic....
