Trying keep up with the other cool overland tundras, I started on my build. First up is getting the power sorted. I plan on tackling the dual underhood batteries next as I think I can cram a pair of dual group 35's under there.

Anyhow, I'm not done on the power side but thought you guys might appreciate the approach.

Goals:
Interior Power distribution so that I don't have to run everything directly to the batteries.
Underhood power for all the external thingies (Lights etc).
Keep it clean so it's easy to trouble shoot.

Todo: Finish installing my Alpine stereo with the KAC-001 module so I can have 8 switched outputs. Think SPOD without having to figure out where to mount all the switches. The outputs show up on the Alpine Headunit. I think it will be cleaner, and its that much less stuff I need to drill holes for. (should have been this weekend but thanks for nothing UPS)

Pics!

This is under the passenger footwell - I cut the foam and put in a 12x9x2.3inch box.

I HATE butchering the OEM boots because they do a good job keeping all the crap out, so I instead butched the truck and drilled 3 giant holes. After I took these pics I did paint the exposed steel.


I used proper water resistant bulkhead fittings.

I then ran 4 gauge power and ground to the inside box and end up with the ground going to a factory ground spot that is just under the air cleaner box. Btw, I ran 2 PG11 fittings for the 4 gauge and then a PG9 for the relay control wires that will head out to the underhood panel.





Here is the blue seas 12 circuit with negative distro.

Don't mind the loom, the right size stuff is on the way. I drilled two holes on the drivers side inner fenderwell and used nutserts to mount my plate. That ground will be relocated to the ground point just under that spot.



Here is where my battery isolator and the underhood power distro is going.


Then I have another plate that is where my winch box will go. Or maybe relays' or whatever I want.

That front plate has a tab that mounts to a nutsert in the core support.


Here it is with the underhood blue seas stuff.


Wondering if I should move this to builds....More Gin and Tonic required.

Looks good. Do you have a fuse on your 4AWG cable going from the battery to the interior fuse box?
