Will the ef civic si harness work in a crx dx? Im switching air box an stuff but not all the plugs look to fit the same for example the speakers to the doors.

 

Bump need help.

 

Is the wiring harness obd0 or obd1 and what motor is in each car?

Edit- also are we talking wiring up the motor or speaker wiring here?

 

so are you using the following:

1. complete civic si body harness? (front frame along firewall to front frame, cabin harness, door harness) etc
2. just the door harness

There are a few differences year to year in those harness as well as the dx versus si as well as the crx versus civic.

I would say you need a factory service manual wiring to help you out.

I'd start with the original crx harness and go from there if it was me.

 

1. complete civic si body harness?
90 ef civic harness into crx dx
