Anyone know what this switch is for?

it is underneath the drivers side dash almost all the way to the (port) side. Seems like an aftermarket switch to me. I just noticed it. Could have been put there by the PO because I bought my 2018 used (off lease from a Toyota dealership). It is in the “off” position. Do I dare turn it on?

 

Do it. Do it.

 

I have one of those switches. Im also curious wtf it is.

 

This.
Or alarm.

 

Best way to really tell is to follow the wires back and see where it goes. Certainly not factory.

 

Sounds like a plan.

 

Certainly not factory? The only thing I have non-factory was a keyless entry installed by the dealer after I purchased the truck.

 

Could also be gps bypass for radio (anytime mods), but you won’t know if you don’t trace/try.

 

It's not a factory switch. I can tell you that with 100% certainty. It may be something the dealer added though, as every dealer is different. If the dealer added it, then it's still not considered factory.

 

Self destruct switch! And as mentioned before, that ain’t factory.

 

That’s the power seats switch

 

Ejector Seat

 

Nope. Dealer installed either for an alarm or for remote start. Probably alarm.

 

We are waiting........

 

It is for alarm, on the old models , it was used to put the alarm control module in learning mod to sincronize with the remote. Now, the new alarms have the learning botton on the windshield, but I asked for a switch when I installed the alarm to temporary deactivate the radar, or motion or proximity sensor (whatever you want to call it) when is very windy or raining and is on high sensitivity.

 

It's the transmission shift controller switch

 

Hold up, we're getting conflicting answers here. It's almost like it's not a factory switch and could be literally anything

*gasp*

 

I’m really hoping it’s not an alarm. Had a nasty experience w a viper system year’s ago that was in my F250 installed by the po.
