Like so many others I want to be able to turn off my DRLs. Eventually I will be moving the DRL circuit to separate lights on the bumper but for now to keep the gate guards happy I added a switch using the OEM "Auxiliary" light switch (fog light switch)
from Man-a-fre and built a harness from the four pigtails.

The two Yellow wires are spliced together and are the switched power leads.
The Black is ground for the LED
The White is the power feed lead.
My intention was to have the switch light up when the lights were on but the switch is set up to be lighted when the dash lights are on so the way I have it wired now the light is very dim. There is a power drop off when the DRL circuit energizes and its constant current isn't enough to light the LED fully. I may just end up wiring the switch's LED to the dash lights but I'm still thinking on that one.
Behind the left light assembly is where the DRL Resistor is located.
You can see in this picture the blue/grey and white/grey wires and the plug that plugs into the resister just behind it. If you wanted to disable the DRLs entirely all you would really need to do is disconnect this plug.
I cut the blue wire (no the FJ didn't explode ) and spliced in the new switch harness. The white wire goes to the blue/grey side coming from the FJ. The yellow wire goes to the blue/grey side coming from the resistor plug.
After pulling the wires, soldering/heat shrinking all connections and looming the harness back to the firewall I ended up with this;
The new harness is on top of the wire cutters shown in the picture and the old harness is below them.
And the switch takes up the blank off to the right of the clutch start cancel switch like this;
Now I can switch my DRLs on and off at will
What I still need to find is the little vinyl letters someone had used here. Then I can put "DRL" on the switch.
