getting accessory wiring through the firewall?

[landcruiser3DP]

anyone got pics of how they got from the battery to the firewall? i am looking to just add a couple always hot dual USB power slots but not sure how best to get it inside.
also any suggestions on gauge of wire?
tips and pics welcome.
THANKS

10ga is probably very overkill, but that is what I use normally for most of my electrical.
As far as a pass tru on the firewall, both the driver and passenger side have grommets that you can use.

I'm a big fan of Sil Glyde whenever I'm workiing through the firewall. It keeps your wires from binding up on the grommet and wiring harness.

THANK YOU. didn't see those for some reason. i should just add some 3M gasket sealant in there when i am done i guess?

thanks man. so you coat it where it is going to have any friction is that it? or do you somehow coat everything before it goes through i guess?

The wire gauge required for a USB plug is so small it will be like throwing a hotdog down a hallway when you go to feed it though the proper grommet. It won’t need lube.

Just a dab will do you. Doesn't take much.

This is not where you should run wires through. Just below it there should be two nipples you can clip the end off and run wires through.

Same for the other side of the firewall:

Pull the wire through and then put a small zip tie on it to seal.
