I am in the process of swapping a b18b1 into my 96 civic, because of budget constraints I am stuck putting in the automatic transmission. I am also using the stock civic wiring harness, the issue im running into is my stock trans has connectors that are not on my b18 trans and there are connectors on the b18 trans I dont have on my harness. Im wondering if my trans will still work. I will try and post some pics later for better reference. Thanks

 

You will need a B18 automatic engine harness and PCM of all the same generation.
