You will have to work around the internals of the switch.

Here is an example of my stock 080 from my '12 Premium

Mine has blank switch plates with nothing underneath but bits of plastic (all above the circuit board) I think it is doable?

How much space is underneath the blank switches?

I'm not sure I have seen the internals of the stock 100 switch (non-crawl models without AVS/RAHC )

undo 3 screws and the entire top of the switch (cover) lifts off revealing the space below the blanks. You will need to cut away the plastic superstructure to figure a way to install an auxiliary switch

So I am a little concerned about going with to 090 switch (although it is what I would prefer and not having useless switches) vs doing the 070. I have a 012 Premium that I have put a 2" lift on and deleted the airbags and suspension...and currently no lights on dash. I don't want to introduce a new circuit that might cause Xmass lights on the dash. Silly concern? or just stick to the 070? Also the ZPC doesn't seem horrible, but I need to get the air intake taken care of so I wonder if anyone has done ZPC with Kuni Lexus of Denver? thanks in advance!

Anyone up to disassembling their 2 toggle 100 switch and posting pics for comparison to the 80 switch I did a few posts above?

I'm curious how similar/dissimilar the circuit boards are.

Thanks!

Here is the 84970-60090, I haven't had a chance to install it yet:

I was just going to post the same pics...….As you can see there is plenty of room to add an extra switch, the hard part will be making it look "factory" or at least professional?
It would be really cool if you could convert the small blank switch into a push switch like OEM

I installed the crawl switch on a 2016 and attempted the OBD jumper calibration and it failed. I did everything exactly in the video but never got the fast flashing lights and now my slip sensor light wont go out...Can anyone advise me on what to do?

What video are you referring to please.

Fitment on parts sites shows 10-19

I've never personally done the OBD method but used Techstream. Are you pushing the ON/OFF button before turning off vehicle? I wonder if you have have a defective switch?

EDIT: Are you on a flat level surface with wheels straight as well?

shmelvin1

The switch is brand new, and the 4 low works fine, and yes I am pushing the on off button after the sequence, but as I never got the fast flashing after turning back on after turning the OBD jumper between 4 & 12 on and off 4 times It seems unlikely it is the switch?

I will have to make an appointment at the local Toyota specialist ASAP as they already told me they can do it for 1 hour labor, I'm sure it will take less than 5 minutes so I was just being cheap and it bit me in the ****...….

Sorry to hear you are having issue...please keep us posted

EDIT: Do you have an OBD setup like OBD Fusion/Link? You can pull codes to see why light is on. I suspect it reset the calibration but isn't calibrating the new one for some reason.
