4th gen Driving/Fog light switch

I installed the Hella 500's and did not want to cut a hole in the dash to use the switch they provide.
I tried using a flip switch that I fit into the T4R dummy switch but that looked less then perfect.

The Manhattan Beach Toyota dealer recommended that I use the switch from the Tacoma.
The fog light switch for the 03 to 06 Tacoma fits into the dummy port on my 05 T4R and is identical to the other stock buttons in the dash to the left of the steering wheel.

There is a guide on the switch that prevents it from popping directly in. The top guides match but you will need to create a 1/8" notch/guide on the bottom. The notch will be on the back part of the switch port and covered by the switch. I used my soldering iron and just melted it (5 seconds and done) and that worked well.
The location of the notch will be obvious when you see the switch.

There are four connections with the left two as open/close for 12v to the relay and the right two connections are for ground and 12v from dash lights. You can splice into the dash light lead from the next switch over so that the button (it does have a headlight picture on it) lights up in the same amber color as the others when driving at night.

The plus side of this is that I don't have an aftermarket light switch for my Hella 500's and I really like the clean look.

The down side is that the dealer charges $46.61 plus tax = $50.46

I think the clean look was worth the price.

One added thing to this. The switch comes without the harness and the dealer wont sell you just the one plug but only the entire dash harness. You are left to connect your wires directly to the prongs or find the harness.
I found the wire harness plug at the junk yard (bring your switch to match it up) for $15 and ran the new wires into the harness and that plugs directly into the new switch. Very clean.
The harness that fits into the switch is the same style as the one for the "RSCA OFF" switch.
The switch is actually handed by a notch in the connector. There is a left and a right and I know this because I grabbed the wrong one. So, I just filed the guide for the handing off and it fit in nice and solid. The clip connector is not effected as you are only removing the raised guide notch on the harness.

The switch for the "RSCA OFF" is handed opposite of the new light switch so you cant mix them up. I used the RSCA switch when I was at the junk yard to match the connector and when I got home I discovered the handing issue. Razor knife took 30sec to fix this.
