G500 Switch Panel Wiring
I’m in the process of building up my 2002 G500 into an overlanding rig. I’ve bought a switch panel and am looking at how to wire it up. My newer 5th Gen 4Runner was pretty cut and dry as to where to attach cables and which fuse to plug into but with the G500 it doesn’t seem so. With the battery being inside the rig, I know I can tie into the battery posts in the engine bay but I’m not exactly sure which fuse to tie into as there isn’t exactly an “ACC” fuse labeled in the fuse diagram and there aren’t any engine bay fuses. Any help on the best way to go about this would be appreciated. Been searching online for a few weeks but haven’t really seen anything that’ll help me for my model year. Thanks.

Plenty of switched power fuses in the fuse box under the glove box. If you want constant power but don't want to tap directly to the battery or the battery posts in the engine bay, then there is a constant power fuse box in the side of the driver side dash. Super simple to use an add-a-fuse for this. Just make sure there is enough power, depending on which switch panel you use.
Plenty of different circuits you can use - just decide if there are any circuits you rarely use or don't use.

In F34 (driver side dash) you can use (Check constant vs switched power):
23 - Rear Reading Light
28 - Interior Socket
34 - Tele aid
In F2 (driver side dash) you can use (Check constant vs switched power):
6 - Rear seat heating module
in Front SAM (N10/1) you can use:
44 - Cell phone cradle
47 - Cig Lighter
64 - Radio/Command
