Hi I need some help in installing a laser park pro, i have found where the wires come into the car on the passenger side but dont think there is enough room to fit what i need through there, plus difficult from the engine area. I have found a cap on the same area as the door switch wires goes through so am thinking of using there as nothing seems to go near there that could damage the wires.

I want to put the buttons and led in the cigarette ash tray (drill the holes into it etc) as this will be easy to replace when i sell the car and also hides away nicely since i cant find a way into the air vent where i originally wanted to put the led and buzzer.

lastly which wire is ignition on and which one is earth as i want to attach to these to so that when the ignition is off the unit is off.

If anyone has had experience of putting one of these in there car i be grateful.

many thanks in advance

anyone installed anything that requires going into the car from the engine area?
