accessory lights on single add a fuse?

    hey all,

    I just bought an 06 tacoma AC, with the 2.7L 4cl w/ a manual transmission. Been looking a while to find the right tacoma and excited to finally have it. Now I'm naturally looking to accessorize it. It didnt come with fog lights and i quickly bought a set off of Amazon for cheap. I started researching, including viewing what others have done on this site with rigging up fuse blocks. I started thinking I was going to go that route, and add more lights, including some high end back up rear bumper lights, and eventually a hidden bumper mount led bar. Im itching to use up the blank switch locations with useful stuff. I bit the bullet and ordered some rigid SR-q's for the integrated bumper lights, and I bought some CH4x4 switches for the rear bumper lights, and the hidden front bumper light bar (that I intend to buy in the future when I have the money).

    I have decided though that building a bussman or blue sea fuse block is too much for me to handle, and not really necessary, at least not for now. I have seen a few of the comprehensive guides on here for building them, and its overwhelming. So, I plan to hook up the two sets of lights (three in the future) the old fashioned way by just using the provided wiring harnesses and mounting the relay's in the engine compartment. I will just use some wire loom and try and tuck it away as neatly as i can. However, where I am needing some help is with the switches.

    I bought two of these for a clean look in the cab (one for the rear bumper lights I have and one for the led bar I do not have):

    https://www.amazon.com/Toyota-Switc...3686&sr=1-1-spons&keywords=ch4x4+tacoma&psc=1

    The fog lights came with a switch that looks factory enough for me so I plan to just use it.

    What I cannot seem to figure out from the research I am doing on forums and youtube, is if its possible/smart to tie these three switches all together and tap into the dash fuse panel with just one an add-a-fuse? And if so, which fuse should I tap into if I want the lights to work independently with the key is in the ignition (I have seen guys use different ones).

    I think the answer is yes, but I do not want to start soldering these switches together without knowing for sure.

    One thing that has me questioning this, is that the cheap (Winjet) fog lights have a different set up than the expensive (rigid) rear bumper lights. The fog lights seem to pull their power for not just illuminating the switch but also operating the lights from the under dash location (there is only one yellow wire going from the relay to the switch - which i think is the trigger). Meanwhile, the Rigid rear bumper lights have three wires (hot, trigger, and ground - i think) all going to the relay from the switch.

    With the fog lights pulling power from that common circuit, would it be best for me to keep it on its own add a fuse, but put the other two like switches an a second add a fuse?

    Another question on the subject (sorry I probably have too many of them for one post ) ... any reason why I would create an issue by not tapping the rear bumper lights into my reverse lights, like Rigid suggests (wiring diagram attached)? I don't like the idea of tapping into them for one thing, but aside from that, I want the lights to come on and off with the button, regardless of what gear I am in. When I have my duck boat on the ramp, I'd like to have the lights shinning even though the truck is in first gear, so I don't have to worry about relying on the parking break.

    Thanks for the advice in advance fellows!

    Yes you could wire all switches to one add-a -fuse if: the are to be switching a relay (pin 86).
    Since you have an AC you have 2 fuses that'll never be tasked, the rear power windows. Check the cab fuse box behind the coin tray (tray comes off, open and pull up)

    Thanks for the reply!

    Attached is a picture of my under dash panel. Are the two circled the ones you are referring to?

    Yes, those circuits are in there, but not used, in the access cab.

    Yes since you are using a switch rated at 3 amps, you will need to use a relay, but you can tie all of your accessory lights to an add-a-fuse. Relays take very little current to trigger.
