Disclaimer: I'm not responsible for anything you screw up from
attempting this mod. I'm just showing how I personally achieved the
desired result. I'd say this is a 1 wrench mod.


I've seen this mentioned numerous times but I have yet to see an actual
write up. I decided to do this using easy to find household items and
tools so the conversion cost should be free.

Items needed:

OEM Toyota momentary switch such as the VSC Off switch
small household staples

Tools needed:

Small pliers
Tape measure
Wire cutters if not part of pliers
Small metal file or nail file


I'm showing pictures of an OEM Aux. Light switch and a VSC Off switch
for comparison purposes so you have an idea what you're looking at.

To start with, you'll need to open your switch up. You'll see there are
four small recessed tabs, two on each side of the switch. Insert
something small like the end of your pliers and pop each one loose. Be
careful when you pop the inner part of the switch out, you don't want
anything flying anywhere.

Here's a picture of both switches with their innards removed. Note the tiny wire in the black switch.

Here are the innards. Note the small Z shaped wire on the left side of the closer switch. We'll get back to that as well.

Okay, now that you've seen a few pictures, I'll explain what you'll be
doing. The two wires I referenced above are NOT included in OEM
momentary switches and will need to be made by you to make your switch
act like a regular on/off switch. I found that small staples from my
household stapler work wonderfully to make the two needed wires.

To make the first wire, bend a staple straight and cut it to 13/16" long.
In the picture below you can see the very small wire above. That's the
stock smaller wire, but the staple works just fine even though it's
larger.

To make the second Z shaped wire, you'll bend half of the staple
straight and bend it back to make the Z. Below are the measurements of
what you should end up with.
1/4" -- 7/16" -- 1/8"

Once you have the second wire bent, take the file and smooth off the cut
end of the 1/8" leg. You don't want a sharp edge here since this will
need to slide on the plastic inside the switch.

Now that you have the two wires made, you need to put them in the
switch. Take the first straight wire and place it in the two slots. The
wire just rests there, nothing else is needed. Take the second Z
shaped wire and insert the longer leg into the small hole next to the
first wire. Face the shorter leg towards the button side of the switch.
Ignore the grease on the shorter leg in the picture, it's not
important. Also note the white piece of plastic inside the switch.

The white spacer will need to be removed from the switch for it to work
properly. You can do this before or after you insert the wires. Just
make sure you remove it at some point.

In the picture above, you'll note the Z shaped wire is slightly angled.
Rotate your wire a little so it looks like the picture. Take the
innards part of the switch and snap it back in place in the housing
while not moving the housing. Now your switch is back together and you
should be able to press the switch in and have it lock in place. Press
it again and it extends to it's full off position. There's not much
difference between the on position and off position, but it's
noticeable. You now have a momentary switch that's been converted to a
normal on-off switch. Good luck!

Once I wire this button in my truck, it will allow me to turn off all of my traction control nannies. The newer trucks have buttons like this, but us older trucks have to fend for ourselves. When new, the button just presses and releases and only sends out a quick signal. Think of it like a horn on your truck. When modified, the button stays on when pressed. Press it again and it turns off. Think of it more like a light switch in your house.
Hopefully this weekend I can do a part II and do a how-to disable your electronic nannies in the truck.
