Hybrid engine bay 12V accessory power supply

I’m installing a light bar on my 2023 sequoia hybrid this will apply to a tundra as well. Where is everyone pulling their power supply from? Is there a good spot to pull from in the engine bay or is everyone running a distribution block from the battery. Tried searching but didn’t see much. Thanks.

 

I also couldn’t find anything for tapping into power under the hood.

Here’s what I did instead for a compressor. https://www.tundras.com/threads/arb-compressor-fender-well-mount-for-hybrid.117757/#post-3078766

 

Thanks for the quick reply, good info here.

 

Here is where I found a 14v supply ignition on only. So powers off with truck it was an unused fuse location, trying to figure out how to get a wire through without messing up the lid or voiding warranty.



looking for small water tight through plastic connectors or plugs to run wire through back of lid, as I want to keep that fuse box water tight?

 

I'm looking for the same. 1793 hybrid. Will be wiring up rocker (rock?) undercarriage lights, stealth led bumper and airlift compressor. At this time, the airlift and rock lights will come into under rear seat are via grommet on passenger side and run to terminal block blocks next to battery. Unsure of stealth lightbar yet. I may run them all into the cab near the battery by drilling hole and using a bulkhead fitting.

I have a few weeks until all parts gathered - plans subject to change.

I am considering consolidating the fuse/relays with the following:

I don’t believe these boxes are watertight.

Here's what I did and notice that I just pushed the wire through the box where all the other wires are going out.

 

like your setup.

I didn’t see much open on that side so I was sticking to other passenger side box since that is where you jump the hybrid from weird little tab to put clamps on cables on to jump.

May not be water tight, but from all the dust under the hood and bugs seems the engine bay isn’t nearly as water tight or dust tight as my 2014 FJ Cruise. Sucks the don’t pre wire AUX switches from factory like others do (bronco, new Tacoma). I’m running ditch lights grill light bar, and E1’s straight off the battery, will use the fuse block for the stealth Amber LED light bar I guess. No more room in the grommet hole I used lol.

 

I ordered these to try.
