Ok there are two places I see on driver side to bring my switch into cab.



View attachment 70695

One requires you to slit inner seal and the other you have to make hole through foam under cowling.

Here is switch I have to slide through

Which is better option to keep as much water and moisture out of cab as possible? What have ypu guys with 2012 and 2013 done?

you might need to look at cutting the wire and crimping the switch back on, so you only need to feed the wire thru the firewall, not the switch.

Have to ask, the whole switch or just the wire? I ran my power lead for the CB through the grommet just below the master cylinder next to the fender. It self sealed up just fine. I think there is a cobra CB install howto on here or project-jk that can point out the location I used. If you have to cram the whole switch through have some RTV handy and you will be all set.

I ran the wiring from my sPOD into the interior by cutting a grommet next the the brake booster. The wiring goes inside right above my clutch pedal. You may want to look into getting an sPOD if you are planning on running more accessories.

If you take of the panels on each end of your dash (the ones that sit up against the doors when they are closed), you will see some foam that leads into the engine compartment just under the cowl. You can route wires through there easily with a coat hanger and then route them under your your dash and along the firewall in the engine compartment. Hope this helps! :thumb::thumb:

There's another pretty big hole on the passenger side behind the battery that is covered up by the insulation and some black duct tape like stuff. I know you said drivers side but here's another option worth looking at???

This. Don't try to squeeze that thing through. Use the foam filled hole (open up a wire hanger, tape the wire to it, and pull through) then reconnect the wire either with solder+heatshrink or solderless enclosed connectors.

That is exactly what I was looking for. Any idea where behind the dash it comes out?

If I remember correctly, if you drop down the glove box, you can reach up behind the dash framing and feel it up there from the cab side but I don't think you can actually see it from the cab side of the firewall, I think it's an oval shape about 1.5"'s by 1", you can drop that thick wire loom that runs across the firewall, bend the insulation down like in the pic and feel the shape of the hole behind that tape.

I ran all my wiring through the foam and under the cowling. Works great and looks good once put into the flexible conduit. I'll post a pic later if you like.
