That's an alternator plug, not distributor. Since you have a JDM engine, I'm assuming your using your stock engine harness (round plug), since the JDM harness is backwards. So you have a couple options. You could rewire the plug (put the square plug on the stock harness), you could buy an OBD1 B-series alternator, or you could swap the voltage regulator (part with the plug) from your stock original alternator into the housing of the new alternator.

 

ya i know i dont know what i was thinking when i typed this up i fixed tho
i was planing on useing my OBD1 harness and the jdm plug but will the wire colors be the same just match them up?

 

Yup, the wires will match right up. It's only the shape of the plug that's different.

 

oh ok thx you
