DIY - 2009 Cruise Control for $10, without pulling the steering wheel and airbag

The smaller switch is rated .5A @ 125VAC. Will this be enuf? Thanks!

The current draw in negligible, so any switch will work. Fitting four of the ones I used is tricky. I drew it up in CAD and found that I only had a margin of about 1/8" for the four switches to fit through the hole behind the trim piece. One thing I just realized that I didn't check how much that hole can be widened.

There's not a huge savings in using the OEM stalk; To me it was more about not having to pull the steering wheel to install it.

The hole can be widened A LOT, maybe half an inch on the radius. The catch is the plastic material is like an inch thick. It would make a huge mess to remove it.

PS the switch Im thinking of using is Digikey EG2021-ND.

That's the nice thing about mounting the switches to that removable trim piece - All of the drilling mess happens on the bench instead of in the car.

Here is my switch install showing the radio shack numbers. Note: I havnt tried this out in the dash to see if my hole position is correct!

Looks close. If you look at the scratched cross and circle on the back of mine you can see the center point of the hole and approximate diameter.

Looks like its possible with these switches that they will fit even if they dont make the hole, judging by the standoffs on the panel itself.

Yeah it fits! The switches are on a 3/4 inch circle. The center of the circle is 1 3/16 inches from the top of the panel (as measured on the outside of the panel) and 1 7/16 inches from the right side of the panel. I cut a 1 1/2 inch circle (the diameter of the cutout in the dash)from a piece of paper and laid out the switches on the paper. Then glued the paper to the panel measureing the center point of the circle from the sides.

would this work for any other cars..

Such as?

I would think that based on what we found with the Yaris it would probably be doable for any drive by wire Toyota.

[marcus]

nice...

[bronsin]

IM thinking something similiar will work for all such DBW cars.

So did you have to do more than ctscott?

Take a look at this thread:

It shows what is required to do it with and 07 or 08. Basically, the extra work is running a wire from the switches to an empty pin on the ECM.

Mod is in and working! The lights for CC come on in the dash and the four buttons are working. I really needed this because my feet are going numb and its hard to feel how much to press the gas pedal. Now I can do it with the pushbuttons a lot of the time. Thankyou so much for this idea!

PS The wife and everybody at work were not exactly supportive about this. "Whattaya messin' wit a bran new car fo...yo is gonna RUIN it!" You need to break through this negative energy sometimes!

PPS My car is a 2009 Basic 2 door HB. Made last September. Oh and it is black in color. I think that helped....

I have two sets of resistors and two sets of switches I bought that I didnt use. For $5 Ill send you a set. PM me if intereted.

Hold on just a couple more days and I'll have that module installed. I just haven't had time to rip the dash again. I also have to rethink my clutch switch, the switch broke. That's what I get for going cheap :) Anyway, I'll prolly just buy the oem one. I'll put picks up when I'm done with all of this...
