I installed the G900 Wolfbox rearview mirror security cameras and ran the wires from rear (mounted the camera inside the x5) and also installed the cig plug-in that is supplied into the cig lighter power supply in right footwell for constant power and hid wires in A Pillar, properly, between freame and air-bags.

I swear, my cars are like a girlfriend.
Sometimes its a rough ride, sometimes its smooth motorin'.
Sometimes she doesnt like how i treat her and sometimes i dont like how she behaves.
BUT at the end of the day, she loves it when I am inside her.
