Alright i've got a 99 civic dx with a obd2b b18b1 swap from a 98 integra. I'm going to be replacing the engine harness and distributor but am confused which distributor i need... If i use a d16y7 engine harness from a 99-00 civic, which distributor do i need to use on the obd2b b18b1 engine. The oem distributor for the b18b1 has a big style plug, but the y7 harness has a smaller style plug so what do i do????
