What Wiring harness/ECU do you use for the JDM B20?


Recommended Posts

is it ob1, obd2a, or obd2b? use an itr, gsr, or b16 harness according to whatever obd the head is. you can use a p73(itr), p72(gsr) or b16 ecu.


dont forget a conversion harness if youre gonna convert from one obd to a different one.

that generation of car , the 88-91 civic/crx , the engine harness is integrated into the car. theres no removing it. so you need to use the wiring in the car and change what is different. OBD0 and OBD1 arent THAT different. get an OBD1 swap.
