So I have this b series harness that came from my my b18c and it came cut up so I went to look for another wiring harness came across this 2000 civic ex harness complete but w some plugs broken. I was just wondering if im able to replace those plugs w the b series plugs. I also have a 1999 non vtec dx wiring harness and wondering if I can use that as replacement parts aswell.

 

What car are you putting the swap in that will decide what harness you can use.

 

I’m gonna be swapping it into an ek civic coupe

 

Use the engine harness that CAME with the chassis that you intend to swap the engine into... and if it is missing, one JUST LIKE IT. If you have a '99 Civic EX auto chassis, use a '99 Civic EX auto engine harness. Then, add/subtract or change/lengthen any plugs that need to be altered. Use all of the plugs from the OBD-1 engine harness that you can.

 

I’ll end up using the ex harness bc it already has vtec plugs on em and the harness that came w my car is non vtec so it’ll just be easier to use the ex harness and fix the plugs using the obd1 b series harness as a replacement parts.

 

So just to be clear its fine to use the b series obd1 plugs and re wire it to the obd2 ex harness
correct?

 

Correct

 

Absolutely.
