For my new small project i bought a 94 ls off my friennd that had a blown lsvtec motor in it for cheap...i was planning on throwing in the 96 gsr i had laying around.... after getting everything all set i noticed the harness that came wit the 94 lsvtec motor did not work on my 96 gsr. is the only haress i will be able to use a 95-01 gsr or can i use a obd2 ls harness since the vtec is already hard wired into the cab. any info helps thanks....
