I have a JDM d15z1, i am installing in 88 civic sedan. I have a P07 Ecu and i just got the motor and found that the JDM VTEC Solenoid has no oil pressure switch. How do i wire it up? I already have a harness with both plugs on it, in other words i have the oil pressure plug wired up but i have no where to plug it in to. Is there a way to wire it up without a oil pressure switch and not get a check engine light?
