I am getting a 99 gsr swap, and I think I am

Supposed to use the harness from the 97-98

Ex harness, but I need to make sure, plus

What ecu should I use? Can I run a p28?

 

What year is your Civic?

 

oh, its a 97 civic hatch.

 

You will need to modify a 96-98 Civic EX/HX harness to make things slightly easier.

 

yea, I was reading about that, but what about the ecu? What's the best option?
I mean, as for getting it chipped, is there gonna be a problem using the p28?
I heard p28 is easier to chip than other ecu's, but not really sure. Thanks for the info

 

just get a jumper harness so that yo can use the p28

why wont you use the same wiring harness???

 

If you plan to stay with OBD2A, get a P72 ECU from a 96-99 GSR. If you want to convert to OBD1, then get a 94-95 P72.

 

I have dx wire harness.

 

Obd2a p72 it is. I wanna ref it, so I think keeping it obd2 is in my best interest for now. THANKS ALOT for info. It is greatly appreciated.

 

if you want to ref it then just keeep the harness and go obd2 p72 the like it was aid earlie.
ill run great
