Good morning. I bought an complete ontrac 2+ (less display) from local dealer and am having trouble getting it to power up. I have power to it in the constant power wire but when I turn on the display, I have no power on the "keyed" power wire to "wake it up" if that makessense. I believe it was being used with an integra but I am trying to use it on a compass. Do I need a different display cable for the compass or do I have something hooked up wrong?
