Back up / Reverse Camera Wiring

[Mateo83]

Buying a touchscreen stereo with front and rear camera inputs. It seems like most people manually turn the camera on and off as needed. Does anyone know the wire for reverse to turn the camera on automatically when backing up?

I assume the brake light circuit has a fuse or something in that area.

I've had a couple of rear cameras in different vehicles and all have a separate wire to tap into the backup light wire so it will work in reverse only. On all of these units that wire was shorter than the cable that ran up front. This meant about the only way you could wire it was to tap into the reverse wire as it wasn't long enough to get yp front.

I also have a dash cam with a rear camera as well that displays all the time and when in reverse the parking grid comes on. Uses the same type of wire. For some time in the Land Rover I used a wireless camera unit that saved me from running all the cable.

Does that answer the question, or did you mean something else?

Ultimately wanted to locate the back up camera wire / location I need to tap into so it works when I throw it in reverse. And worn have to manually access the rear camera prior to backing up. I have to run an aid to camera anyway some I’m not concerned with running another power with it.

Tap the backup light at the bulb.(what I did).

If your tester ground is good, you should gets volts when touching the positive lead to one of the terminals. Try unplugging the taillight connector and placing your probe on the open end of the terminals.

Automatic or Manual?

Switch is bad if manual, the contact point are worn if automatic?

^^^ Yep. Do your reverse lights work? If so, there's got to be volts going to them. I discovered that my reverse light switch broke when my back-up camera stopped working.

What is flashing? The screen or something else? Could be normal for your particular set-up.

Sorry to say, Alley…your descriptions are very hard to understand.

Slow down, describe everything as specifically as possible and focus on one thing at a time. There’s always a way this makes sense, but we’re not there yet.

I tested the terminals in my right backup light with my new multi tester. In the book it shows 7#4. When I trested on my 1990 Vanagon I found it to be #2 not 4. I tapped into the wire on 2. I put my manual transmission in reverse and the camera works right away. But the backup light on the right side does not but the left does. Am I to assume the left parking light is using 6 volts and the right should as well but because the right park8ng light has the backup camera drawing power the brake light doesn't have enough voltage to run the right parking light? On another note if I put my left signal light on it flashes normally on the dash but if I switch it to the right signal light the indicator on the dash flashes at twice the speed. I have seen that in my 1956 Chev when I had a bad relay? I am not sure how else to describe it. I currently have a torn rotator cuff so it's a bitch to type.
