hi i have a friend that has a 90 crx he just put a dohc zc in and has been having problems getting it started so he got a si obdo wire harness form pick a part now when he turns the key it turns all of the power off cluster, headlights everything that runs off of the battery and when he connects the positive terminal it sparks what could cause this (it will only shut off if hes on the clutch and tunring the key not by turning the key alone)
