Ok so going through the forum I found a picture posted by Dr Isotope that has all the switch blanks in his tc filled.

Does anyone know what this last switch blank is used for. It looks like some kind of adjustment ****.....

 

Could be a bass ****?

 

I would say bass adjustment...

 

you can put anything you want in those blanks. for example, mine are filled with the black oval rocker switches that have a blue led in them from autozone

 

you can put anything in those switch panels...

even a nitrous button if you really wanted to.... but yea... looks like Doc I's bass adjustment ****.

 

I would agree that it is an adjustment **** for an amp, I take it you just bought the car?

 

I've got an assortment of switches that fit in the sponsor section

 

It is. I recall a post by him saying that he used it to adjust his bass.

 

what lights turn on with the illumination switch?

 

Interior Enhancement LEDs

 

why did you just ask doc i in the first place. lol.

 

i think me thinks that he thought that that **** was something that was a "factroy-ish option" that was installed...

not knowing you can put anything in a switch panel..

 

I think he was trying to ask, what are all the spots for, how many extra factory options use those switch plate specificly. What is supposed to be in the bass **** spot.

I would like to know aswell.

 

that one **** could be used to dim certain lights possibly.

 

looks like thats a Bass adjustment **** to me.

the only things that you can get from Scion that use the switch bacnks are the aarm system, Fog Lights and the interior LED lighting. which would leave you with an empty spot for whatever you wanted to put in there. the xBs only have the 3 blanks and can have the same 3 would fill them up...

i have all my interior lighting on my Scion illumination switch and the Alarm system and a third autozone switch going to my engine bay lighting, nothing in the 4th one yet though.

 

if you look on the fuse cover you can actually use the templates on the back of them for three more switches for a total of seven...... but why would you wanna reach down there....

 

thats not so far out of reach for a simple accessory switch,

 

Thats true but me legs come across that panel when i get in

 

I would say that **** is for turning the valume up and down on the passanger.
