ok so i have a ls/vtec setup with a 00 si head and a 97 ls block .. and i was curious what kind of wiring harness should i use. can i just use the oem 00 si or a 00 gsr one ?? does it have to be obd2 ? do all the plugs match up the same ? just curious ... any feedback is welcome

 

i would use the 00 si wiring harness, you could put a obd1 harness but your have do change some things , your better off putting the 00si harness and getting a obd2 to obd1 conversion kit....

 

I have the same problem,same setup as well.Anyone got answers?? =/ I've tried emailing 3 different sites but can't get any straight answers...

 

Year/make/model? Ecu you'll be using?

 

89 Crx si with zc swap (thats how I picked it up) I have a chipped P105 Chrome ECU.
