Permantly +12VDC?
Hello All
I have my Garmin Dash cam currently wired into the overhead light at the mirror that comes on and off when the car is on and works great. However as I have to leave my car parked in London in the day, I have bought a parking mode cable so that it will record any movement when the car is off and parked etc.
I need a constant +12VDC when the car is off, so before I pull a cable in from the fuse box, does anyone know a good source for a permanent power feed?
Thanks

The OCP is supplied from K40/4 Fuse 38 (7.5Amp) to pin 4 on N70 OCP [Red/Violet]
I'd presume this is constant as the OCP has power all time. If you measure it to check
Mines currently switched like yours so is probably currently taking power from pin 7 or 12 the radio amd or mirror
