Will a 1998 B18B ALTERNATOR bolt up to a B18A?

My friend is currently building a 98 hatch but he is having trouble with the alternator. he has a B18A from his old integra and a DRAG3 kit on it. he is using the 98 Civic harness and the alternator plug has 4 wires. the B18A alt has 3 wires with a totally different looking plug.
TIA

I'm pretty sure there are two grounds and you can get rid of one I forget which one I had the same problem when I swapped my b18b into my 96 civic ex. hope this gives ya some more info to help ya out

 

i think a b18a from a 92-93 integra (OBD-1)will have the same alternator as a b18b

I dont think it will work. They are the same size and have the same bolt pattern but the connectors are different.

 

car: 1998 DX hatch

motor: B18A

engine harness(motor to shock tower): 1998 Civic harness

so my friend can bolt up a OBD2 B18B alternater to the motor? i told him to use the 98 B18B alternater so the wiring plugs would match up. then i told him to use a OBD2-OBD1 jumper harness so he can use a OBD1 LS ecu. am I giving the right advice?

 

ive got one from a b18a on my b16 it fits no problems.

 

The alternator from my 97 B18b has a square plug so I traded them for a 91 LS alternator and it has a round plug and it worked...
