One place to run multiple "Accessory wires"

[johndoug]

I need an accessory wire for a dash cam, DC to DC charger, and about three other things now, and I am sure there will be more in the future. I can't see running all these to the fuse box. Where can I find one main place to run them all?

Just run a large(ish) gauge wire from the battery post to a fuse (or circuit breaker), then into the truck through one of the many grommets in the firewall, ending in a multi-outlet fuse block (Blue Sea is what I use) tucked up under the dash.

This (with a relay to only make it hot under switched power), is how I run my heated seats, dash cam, radar detector, and tablet USB

I think I worded this wrong, I don't need a place to hook up a bunch of devices, I need a place to run multiple wires to a point where 12VDC is present when, and only when, the ignition/ACC is switched on. I do not need to power the devices from here, it only tells the devices when the car is running and when it not.

Ohhhhh! You're looking for a switched 12v+ signal.... I used a wire coming off the BCM, I believe white w/ a blue tracer (or is it blue with a white tracer....)... It's larger and near the bottom... I'll poke around and see if I can find the thread that lead me to it, it was an alarm install thread I believe...

For example, one of the devices says this:
Positive wire goes to the battery ground wire goes to ground then there is a smaller wire that goes to an ignition wire or you can get an add a fuse and find a fuse under the hood that turns on with ignition so the light switch isn’t on all the times or you can add another switch to turn power on to main switch .. then the when hooking up lights you hook ground to a ground on vehicle and then you hook up the positive to whichever wire you choose see less.

If i was just doing one or two things it would be simple, I will have around 5 or so.
