    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.
