I swapped a b16a sirII in my 93 civic coupe and I used the wiring harness that came with the b16a. I heard I could have used my ex sohc wiring harness but I sold it thinking the b16 harness will work. I heard I'm supposed to use a American engine harness either the ex sohc or del sol. My engine turns over with the b16 harness but no spark so it won't start. I thought it was the coil So my question is can I use the jdm b16a wiring harness in my ex civic or do I need a ex or del sol harness American made engine harness. Or am I in the right direction and it is the coil and not the harness at all. Please someone help me I need to buy the harness if that's what I need or the coil but I want to know before I do buy anything.
