I have an '03 excursion and im not sure where too put the plugs to power the monitor. They are two small red colored male plugs. Do I have to get some female connect of the same style and splice them into the ignition wires? If I plug the OBDII plug in the monitor turns on but doesnt read anything. Is it normal that I have to unplug the OBDII connector to start the truck? Does it only do that because I dont have a 12V power source hooked up to it yet? On the pyro there are red and yellow wires and on the wiring harness for the monitor there are pink and brown. Which go to which?
