Firewall pass through

I’m needing some power for my radios and I’m curious if anyone has figured out how to get wires run directly from the battery, back through the firewall, into the cab on the 4th gen. I’ve looked around the engine compartment and don’t see anything that would work.

 

Your firewall location is the same as this:

Awesome! Thanks Snickers, will take a look and work on it. Cheers!

 

Theres 2 large ports & multiple small ports also, easy access....
One large boot directly behind the battery...
Would probably need to remove battery to access that one..

the easier boot to pierce is on the driver side, easy access, giant access....
If you chose driver side, you can hide wires under the wiper cowl..

Then there's some smaller .5 1.0" rubber plugs you can also access...

 

Also, there's the AUX switches and their outlets in the driver's side kick panel.

 

Thanks Slater, will take a look in those areas too… cheers!

 

That’s an interesting option, will have to see if they are compatible with the power input required by my new radio.

 

Connector is labeled R27

That's assuming you have aux switches, correct?
Seems like a waste of a switch to me, why double switch it when super easy to run wire...

 

YOU rather run the risk of stripping the cover of a wire while inserting it, or worse stripping adjacent wire bundle that cost more then 1K to replace. But what do I know...

Where are you getting the wiring diagrams?

Thank you sir! This is exactly what I needed to make my ecoflow alternator install a breeze.
