On a recent camping trip sleeping in the 4Runner I realized it's a bummer having to find the keys and turn on the ignition to be able to roll the main windows up and down. I wanted to create a mod that would let me change the truck into "camping mode" where the windows can be operated at all times. But I also wanted to be able to get out of "camping mode" easily.
Following the thought processes in this
power window modification thread I decides to use a switch to bridge the always-on and key-on 12V sources for the power windows. Wiring diagrams are in that thread if you're interested.
Found the fuse block by the driver's left foot and pulled it out. Had to disconnect one or two things to get it to move much.
Looking for the 1C connector on the back which goes to the power window circuit
This guy right here. The 14ga blue wire is the always-on power and the 18ga blue-red is key-on power. I put vampire taps onto those wires where the arrows are shown and wired them to a simple 2-prong connector.
Built a switch and harness to connect to the two tapped wires. This is a window lock switch from a 1st gen 4Runner. I added a fuse holder for a couple of reasons. This switch bypasses a relay which is normally used to control the power to the windows. I was unsure if this would be a high current operation and if the switch would handle it happily.
Turns out that a 5A fuse is sufficient if only one window is run at a time. Once two are engaged the 5A pops. A 10A fuse allows me to run two at once which I normally won't do anyway so now I know that we're running in a <10A scenario.
When the switch is pressed inward it opens the circuit putting the truck in "normal mode". When pressed outward it closes the circuit and we're in "camping mode".
