well I just got a crx for 200 and I am ofcourse swaping in my ls/vtec from my 97 civic 4dr. I have a complet p28 ecu and engine harness. But I was wondering if I need a conversion from obd1 to obd0 for under the dash. I belive it is like 12 wires you guys know the brown or green connector under the dash. will that just plug in or do I have to rewire it to match. anybody know what is needed I have done some searching and haven't had much luck. Thanks in adavance.

hoping for low 13's

Get the harness and your done. Buy through Chris good seller

 

What model is the CRX? And you always use the engien harness from the car, dont swap the harness. IF its DPFI you convert to MPFI first then use the conversion harness for obdo to obd1.

 

well it is a crx dx still has the stock d15 and harness in it. but I do have a complet 93 civic ex wiring harness and p28 to match I would rather just use that harness instead of doing a bunch of wiring to make a dpfi into a mpfi. It's can't be that hard to use a 93 civic ex harness in a rex can it.

 

convert to mpfi I recommend sending the harness to rywire.com then get an adpater harness and you done. You always use the harness in the car and add the wires not the other way unless you want a car that wont run and have headaches. Plenty of info on here its not that hard

 

well in my last setup I went from a dx harness to ex harness and worked out pretty good actually few things I had to do to pass emissions but all was good and seemed easier then trying to hack up my dx harness.I like the factory look much better then wires here and there and plugs spliced

 

ok end of thread
