Where To Pickup 12v For Reversing Camera

[ricknismo]

Probably a simple question but I'd thought I'd throw it out there.

1. The camera needs 12v that obviously you don't want running all the time so I would pressume you could bum it of the reversing lamp circuit??

2. The head unit has an auto switch function that puts it on the units reversing camera mode with 12v in. I could install a rocker switch but where could I get 12v from in the cab that only is available in reverse?

I don't think there is an ECU pin or fuse ot dash indication. Any tips?

Cheers

the reverse light is of a separate relay not through the ECU so find the relay and wire it up to the HU and u could also add a rocker switch so the camera could be turned on even if the car is not in reverse or to disable the camera. its up to u how u exactly want to wire it. note i guess u could get away without the added relay but i have never installed a camera so i wouldn't know

and does the HU have a 12V out for a camera ? if not use the above im guessing but wire it to the camera as well?

if its a pioneer unit - power the camera wtih ACC and take the reverse signal off the light. that way yuou have the camera in motion when needed.

If the camera is of the acc that means it would be on all the time when the car is on and as it is a night one also the little leds would be on when not needed.

Anyone know where the 34 GTR reversing relay is?

You can piggy back power off the reverse lights if you just want it to work when in reverse depending on current draw?

I use a 8 channel external video switcher, but mine has a few extra sources and screens to deal with.

you can get one for under 30 bucks if you look around. or hook up a relay to switch it on . search for Bosch relay guide. it has a lot of good ideas in it.
