Backup cam wiring

Looking to run the wiring for a backup cam.
Looks like the oem wiring harness runs from the tail light to the center of the truck close by the bumper.

Instead or me running a wire to the backup light. I was going to tap into the wire there. Around where my trailer lights connect.

There is a bundle of wires there. Does anyone happen to no which color wire to look for that feed the backup light.

Or should I be looking for it under the dash for the connection.

Thanks

 

It may not be exactly what you need, but I think it's in here somewhere. You can poke through it until one of the experts shows up.

Thanks found it. Good detailed explanation.

But 2 things not sure of if anyone could explain.
1. I understand if I want the cam to come on just with reverse lights.
But if I decide I want to wire it so I can use it anytime driving forward. Does that mean every time the truck is on the camera will get power and be used. And may
shorten the life? Even if the head unit is not turned on. Would still be getting power and in use even if not used.

2. The other explanation the guy said to cap off the extra red wire attached to the
RCA cable that runs between the front and back. Or could blow a fuse.
Well if you are going to cap it off why even connect the back end to anything. So
no worries of blowing a fuse caped or not.
Seems like I am not understanding something right. This was when he installed it in order to have the camera on all the time. And he used a trigger from a wire
behind the glove box.

 

If you put something on constant-hot, yes, it'll be powered up, therefore yes, you're technically counting down. Shouldn't matter much if your HU is actively displaying whatever it's pushing, if you're putting power through it, the circuit is live, electricity is flowing through it, it's "on".

I also found these threads helpful enough I documented. I still haven't decided where to pop my wiring through my cab, so I've been in a months-long holding pattern with installing mine. I haven't been driving much, so no real urgency yet for me.

I wired mine up to be just on the reverse lights, then decided I'd like the function to have it "always-on". Turns out that's what those little red pigtail wires on the yellow video cable are for.

The pigtail on the end that plugs into the head unit taps into the 12v red ignition cable that is part of the wire cluster coming into your head unit. The pigtail on the end by the camera should be soldered to the red wire on the dual red/red-black wire coming out of the camera. (You'll know you're soldering the pigtail to the correct red wire if it has an inline fuse, that little glass tube inside of two threaded black plastic holders.) The red-black wire should be grounded.

For tripping the camera when shifting into reverse, I ran a wire from my "reverse-in" on the back of my head unit all the way through my cab, through the grommet under the carpet behind the rear seat, to the reverse lights in the back. You could avoid this though by tapping into the reverse light wire that is somewhere up front...I just couldn't find it.

Hope this helps.

 

Thanks all.
Had a little time. So ran the camera wire front to back and nice and neat.
Waiting to get the headunit and actual camera in.
Pretty sure a little overkill. But I did not like the looks of the standard cable with the red wire at each end. Just looked very light duty to me. And I did read a review where someone had one go bad.
So I also ran a 4 pin camera cable with it. About 15 bucks more and did not really take anymore time. So have a extra cable if ever a have a problem or want to add or do anything different.

Another choice may have been better to get a much better RCA cable from monoprice for 10 bucks. Then tape a extra red wire to it.

Also thinking ahead and wanted better cam. If I ever was at the junkyard and found a OEM cam cheap of any brand. The 4 pin cable maybe needed to make it work.

 

Great info in this thread. I picked up a Jensen HU with inputs for front and rear cameras, so I'll have a cam up front when I do High Country rock crawling here in Wisconsin....
