Ham Radio Installing Power Cable under the seat

I recently purchased our 2016 Jeep Wrangler Unlimited. I want to install a cable under passenger front seat going directly to the battery to power a VHF FM 75W radio. Ultimately there is going to be a second cable installed that will operate the brake controller, on the driver's side, for towing the Jeep behind our RV.

In the past I have had a fair share of bad luck getting this accomplished. I had a friend, who owned a radio shop, install a cable on my S10 and he managed to drill through the seat airbag sensor cable, $800 later my airbags were working again. On my GMC, my mechanic (who doesn't live nearby any more) was able to route the cable through the firewall using one of the existing cable runs.

I was looking around the vehicle and I haven't even found where the cables are that go through the firewall. One of my choices has been to add a fuse to the fuse block but there doesn't appear to be any fuses inside the cabin.

Is there a way to do this easily? Preferably without drilling holes or compromising the "advertised" water integrity of the cabin?

My other choice is to take it to a car stereo installer, which the dealer recommended.

Thanks
Tom

Here is a guide for the going through the firewall on the passenger side;

Detailed Guide: Passenger Side Firewall Hole

There is also a hole on the drivers side. If you look under the dash on the far left (and high) you should see a black circle. I used a straightened coat hanger to push through and you can see where it comes out under the hood.

Hope this helps...

This is going to save me a bit of change. Thanks.

Is there a similar site that shows pulling the door sill covers off?

So this is obviously going to be slightly more difficult than expected. While I may not be trying hard enough, the side cover on the passenger side of the dashboard doesn't appear to be easily removed.

What are the steps to getting it out other than "grab it and pull".

If there is a picture someplace that shows what to do maybe that would help.

Of course this is a 2016 and they could have changed something.

Thanks for all the help.

Mine was a little tough to remove but it is only held in-place with clips, so it should just pull off. I try to work from one point and work may way around. Interior trim tools may help as well. I have a set similar to this;

Robot Check

I can't really remember if I needed them for this panel. My Jeep is a 2014 and I don't know if anything changed with the 2016.

I had a friend help me get the panel out. What he did was push it a little bit forward which opened up a space between the dash and the cover. We were then able to pry the cover out of the clips.

Wire is run into the engine compartment along with fuses. It still on the floor of the passenger compartment, that will get finished tomorrow.

The radio is a lot happier with solid battery power.

I ran a pair of 10 AWG wires to the battery, one on the plus side, the other on the negative. Both are fused. Some will argue that you only need one wire, the plus, but I have found that by running both plus and minus leads it allows the battery to function as a big noise reducing capacitor, which helps keep down the engine and alternator noise.

Good to hear you got this resolved. If you get a chance, post some pics of the final install. It's always nice to see how folks mounted their radios.

I agree with Phototrek about the pictures. hopefully you have been taking pictures of each step of the install. I would love to see them.

Phototrek, I sort of borrowed your idea, but when I ran into an obstacle, that is a bracket for holding the seat wiring harness, I removed that bracket and then inverted the bracket that was based on your idea. So the Rubbermaid bracket goes up and across and supports the radio from above. I am using two 1/4 by 20 bolts to support the radio body with a couple of wing nuts so I can drop the radio down if need be.
I tried to take some photos, but they didn't come out well.
