well like the title says my friends has a b18c swap in his integra. The car does not get any oil pressure to the head and does not engage vtec but the harness that is plugged up seems to be connected correctly (i mean its plug and play). The engine harness was for some reason switched out to an obd2 harness by some shitty shop and the interior harness that goes to the ECU is an obd1 harness. Now what im trying to figure out is how to DIRECTLY wire up vtec to the vtec solenoid because everything seems to be fine in the harness and im guessing it has no oil pressure in the head because it does not cross over to vtec. IM CONFUSED and dont know what else to try. any help would be greatly apprectiated!
