does ne one now of a site or how to wire vtec or ne diagrams on obd2a P72 ecu in runing ls v so also NEED HELP
grounding knock sensor been looking every where n cant find the right one plzzzz help
 
I am in the same boat. the ls harness is working great so far as everything hooked up. only had to lengthen two sensors. going to a jdm. keep in mind the jdm vs usdm vtec has only 1 wire an the us model has the vtec psi switch also. what engine are u using or did u do a ls vtec swap.. there is a post under technical articles that shows what needs to be pinned to ecu for vtec. very useful.
 
Im running ls v i wired everything now and dont have any cel code but my v tec doesnt seen to engage on ecu (p72) if i tap it to batt it clicks so vts is good what do i do
