Got the whole HX swap in and there is an extra plug going to the ecu! The fuel pump is also not priming. Anyone know whats up with the extra plug. We are using the HX wiring harness and Hx ecu.

 

All HXs are OBD2A, all other '99 - '00 civics are OBD2B, you will need to swap the interior harness as well as the engine harness from the HX.

 

can I change the ex harness, ecu, intake, and exhuast manifold?

 

help plz

 

your gonna be using everything fromy our HX to put in your ex (if that is what you meant, i didnt understand the qs)

including harness, ecu, and idk if you need to swap your exhaust mani, if the ex bolts up to your hx then my guess is your fine

 

so a 99-00 interior harness is all that is needed? anyone have a write up on how to swap interior harnesses?

 

i didnt realize HX swap was such a mission...

 

yea me neither. lol
