I recieved my new guage on friday.Hooked everything up but guage seems to be not operating properly.When the red power wire is hooked up to acc power and the obd port is plugged in it activates the head lights and dash lights come on without evan turning key on for power.Itried to tap into the power wire of the boost guage and when i plugged in the obd port it activated the ignition to on position without evan turning the key again.I dont know what else to try .I think maybe I got a wrong guage or a wrong wire to obd port.If I just leave the red wire off and plug into obd port it will power up when i start up engine but when i turn off engine it will go off and not turn on on startup again,unless unplug it and plug it back in before start up.Any help would be appreciated.Thanks
