I've searched the entire web for this part.it should come with my ECU "adaptronic " but i bought it used.i work way to much to spend hours online reading through countless dated fourms.tJust trying to plug in, can hi and lo to use the gauge art gauge.but don't have the pin connectors. where can i order them? part ### and do i have to unplug harness from ECU to plug it up correctly.i stuck wires in labeled holes and it works as it should.just want to finish this easy job up correctly.since po left ecu just laying on carpet with no mount.... thanks
