I am in the process of installing a rear camera for my truck camper.

I am working on my 85 K20 with an automatic transmission.

I need to tap into the backup lights.

Rather than run a wire back to the taillight I was wondering if I could tap into the wiring underneath the dash.

If anyone knows where the wires are I would appreciate the help.

Thanks so much,
Jake

I am not sure that wiring will be under the dash since nothing in the cab actually depends on it - my understanding is there is constant +12 going to the switch on the transmission (which closes when you move the selector to "R") and then from there it goes right to the reversing lamps. The closest point to grab that signal might be at the transmission itself.

My rear camera needed one power supply when the vehicle is on and one signal (reverse light) to turn it on. Is your setup similar?

If you can't find it put in a switch that you can use to turn it on anytime you want.

Flip switch, camera comes on.
Put truck in reverse and back up.
Turn switch off.
Put truck in drive and drive off.

Yep -- the screen for my camera has an on/off switch on the face of it.

I have a dump truck that has small side mirrors. I installed a camera that the screen is a rearview mirror. It was able to be set to stay on any time the truck is on. It did connect to the backup lights, but that just turns on the lines to help with parking. It works great, but can give you a little motion sickness if you watch it too long going down the road. It has ad HD display that is so clear.

I have a back up camera on a choptop sled. I have it powered with the ignition on all the time. You should have open ignition slots on the fuse block to pick up ignition power. Like yours mine has a switch on the unit if I want it off.
