Alternator Swap, 94 to 87.
 

I tested my alternator, not doubt it's fried.

My buddy has a wrecked 94 Civic SI with either a B15 or D15(whatever it came with) and I have already pulled the alternator from his car, but I haven't looked at the one on my car.

Is it a straight swap; do I need to re-wire the plug?
