Tapping into fuseblock

[Yukongk]

I'll be installing a new backup camera system. I'm going to need a power source to power the monitor and don't feel like going to the battery. Can anyone offer some guidance in wiring to the fuseblock? Should I piggyback off of the radio fuse? It's a 3.5" LCD monitor. Thanks

You can tap into the positive wire on the front or rear power outlet. Those fuses should be hefty enough to be able to handle a back-up monitor.

Does it call for a constant or a switched 12V source?

I just ordered it, so I'm not sure. The online instructions are crap though and doesn't say.

You can always tap to one of the studs in the fuse block. I would hook it up to stud two so it is switched. Also a good time to hook up your charge line if you need 12 volt out of your 7 pin.

Being that it won't be used continuously and will only power on when you put the truck in reverse, it would probably need a switched power source.

Just for your information, I case you didn't know, a switched power source is an accessory that only powers on when it is needed. Like your windshield wipers, horn, headlights, etc. a constant power source is something that is always on. Like your driving aids, power outlets, stock or aftermarket radio, etc.

Either way, keep us updated and we will be sure to help you out more!

I would wire it to the reverse lights so it comes on automatically. This is how I wire them when doing them for customers.

Thanks for the explanation! It is def switched.

I'll be connecting the camera to the reverse lights (already have the wiring from my last camera, so I'll splice in when I remove the old camera). I was under the impression that the monitor would need its own power source though. But like I said, the instructions are crap.

For the monitor, I would splice it in to the ignition wire in the radio harness. Its a dark green wire, plus its also a RAP circuit as well. That's where I spliced in for power for my overhead monitor and my center console mounted DVD player, and its worked flawlessly for 7 years now.

That'd be very convenient since the radio harness is in the vicinity. I'm assuming that I can go directly to the green wire without a fuse, since the radio is fused in the fuse block?

Thanks

Yes, you should be fine tapping into that wire. Personally, I would solder a wire into a splice just so make sure it never wiggles itself free and causes shorts.

Yea I usually solder. So this wire is dark green and not yellow like I was thinking it would be....?

That, I do not know. Maybe someone else can chime in with that answer. If worst comes to worst, you can always look at the Factory Service Manual and trace the wire.

Just probe the wire with a test light and turn truck to run. If power is not present until the key is in run/acc then it is switched. My wiring did not match the schematic I got from my dealership so I probed all my wires when I did my DD conversion.

I have a 2001 Suburban and the ACC/Radio wire is dark green for mine, but definitely probe it if you can first to make sure.

Camera kit came today. I am going to run the power for the monitor to the reverse light, just like the camera. This way the monitor only comes on in reverse with the camera. Do I need to fuse this run of wire?

It never hurts to have a fuse but you shouldn't need one. I like thermal breakers as there is no fuse to change just wait 5 seconds and it will power again. So much easier for under $5.

If connecting the monitor to the reverse light wire, you can splice into a light green wire on the drivers side of the dash, its a harness that runs up the windshield post to the rearview mirror. You can grab the harness in the dash right above the fuse panel when you pop that cover off. Easy as hell to get to it.

Well, the install is finished. I found out that the monitor turns on when it detects a video signal and off when it doesn't. There were a few different dark green wires in the dash, so I just spliced into the radio harness pink wire that said "Ignition Switched 12V" and spliced into the radio harness ground wire. Worked out well! Thanks for the help guys.
