Swapping a GSR into an LS
 

OK just bought a jdm gsr obd1 longblock today. I am going to be swapping it into my obd2 LS. What am i going to have to do in terms or harness and getting vtec to engage properly. Can i use my obd2 ls harness? i need a way to engage vtec, knock sensor, etc. I'm running an obd1 p75 and obd2-1 harness at the moment. p72 is on its way and is obd1. What do i do?

obdi one harrness buddy way to go, as for vtec just swap the harness you should be fine if you got a p72..and no you can't use your obdii harness at all if worst comes to worst my man call up skunk2 and get a obdII to obdI conversion harness and splice the plugs on your disturbed thats the only real differences in the OBDI and II oh and the II comes with two oxygen senors.. that should be it hope that helps.
