I have a obd2b b18b1 that I would like to drop into a obd2a 1998 civic ex what would I have to do? I know I have to use an obd2a harness but will everything plug in correctly? Are there any different plugs or things I have to modify? i heard something about the distributor plugs being different how would I fix that? All help is gretly appreciated thank you

 

1. No
2. Yes
3. Get the obd2b em1 civic si engine harness or get an obd2b ex engine harness with 8 pin to 10 pin distributor adapter

 

I read that you cant use an obd2b harness in an obd2a car??

 

not sure what tony is doing there. use an a harness. you can swap your plug onto the b series distributor. do some homework.

 

ahhh...my bad I read it wrong. I thought you were using an obd2a engine harness in an obd2b car.

my bad.
