Dedicated accessory power in a '15 RAM 2500?

I want to run dedicated power for my dash cam and trailer TPMS in my 2015 Ram 2500. I'd planned on tapping the power from the fuse panel, but then discovered that it's been moved to the engine compartment next to the battery.

How are you guys hooking up your extra gear? Does anyone make a pig tail that can be plugged in between some component's plug? I'd rather not splice into the wiring and void the warranty (brand new truck).

Yeah, I could just run the wiring from the dash cam down to the cigarette lighter, but that looks so cheesy.

All my permanent accessories are hard wired into a fuse block in my Ram 3500. get a fused accessory box from an auto part store and mount it under the dash by the knee plate. Run 12guage wires from the battery with inline circuit breakers and your set. There is a hole in the firewall where the clutch pedal would be mounted. If your handy it's less than an hour of work.

I would check out Geno's Garage .com, they offer a device called Painless wiring fuse block. The Painless wiring block is offered in 3 or 7 circuit that offers fused power connections for electrical attachments.


I have one on my 08 and I installed this back in 2011, to operate my air bag compressor and an extra 12-volt supply for my radar detector. What is nice about the Painless wiring fuse block is they protect the TIPM (total integrated power module) that Ram uses for the wiring on the truck.

In my Ford, I ran the power for dash cam and tpms to the back of cig plug.
Going to do the same in my ram 3500.
You won't void the warranty by splicing into the cig plug.

The other option is to run a wire through the clutch knock out, drivers firewall to the battery.

Steel, Jim - several guys on the TDR forums recommended your Painless wiring block suggestion, so that's probably how I'll go.

Kenny - I can't get to the cigarette lighter. I think I'd have to disassemble part of the dash and it's just not worth the risk of tearing up the new truck.

I'll buy the 3 circuit wiring block and run it through the firewall.

It's 10 mins work to get at the plug.
A third the work of pulling through the firewall.
I have to remove my radio for other reasons anyways, so I'm there anyways!

Seems a good solution, though I haven't tried it.

It's really easy to get to the cig lighter in the Ram. First time will take about one minute and once you've done it the next time takes about 30 seconds.

At the top of the facia above the Uconnect you'll see a little "tray". Remove the rubber mat in the tray and you'll find two "star" screws there. Remove both screws, hold onto the tray edge and just pull (sorta "pop it") it out. The entire facia assembly will come out and you can easily get to anything behind it...including the lighter wire at the lower left corner. The first minute of this YouTube video will show you how easy it is to remove:

For your dash cam install, remove either the left or right windshield pillar cover (two bolts, 8 or 10 mm IIRC). There is a big hole that will now be exposed at the top corner of the dash where you can run the power wire for the dash cam.

If you're using the cig lighter plug for power, just run a big heavy duty tie-wrap (18-24 inch) down through that hole. You'll see it come out below the dash and you can tape the cam connector end of the power cord to the tie wrap, then pull it up. Once your wire is pulled through the pillar area, just gently pull down on the very front of the headliner and work the wire in above it.

Works great and you'll never see any wiring except for the last couple of inches where it comes out from the headliner to plug into the cam.

Unfortunately, the fuses are in the engine compartment next to the driver side battery in the new rigs. I was going to do this, until I found the fuses were no longer by the driver's door!
