2012 Toyota Tundra Double Cab Alarm/Remote Start Wiring

Not sure of it's the same as 2011 or 2010, but can someone provide me with the wiring diagram for this vehicle. Also, the key has a "G" stamped on it. Not sure if it affects anything. It does have an immobilizer installed.

Plan on using the Viper 5901 with the XpressKit PKAll.

Thanks!

The "G" stamp on the ignition key indicates an 80 Bit Encryption system.  The PKALL will work as long as it has a minimum of Ver 4.0 firmware.

DOOR TRIGGER       BROWN (-)       @ BODY ECU, (WHITE, 26-Pin Plug) Pin 24, NOTE #3

---

This door trigger wire is only for the front driver's door. When opening the other three doors, the alarm will not trigger, nor will it recognized them as open when arming.

I'll have to locate the other 3 trigger wires, and diode isolate them. Is the 2011 wiring diagram the same for 2012?

With all current Toyotas go to the dome light switched neg feed (-).
Usually a 2 or 3 pin plug at the fascia fusebox. This will pick up on all doors and shuts down immediately the vehicle is locked.
Officially it's a blue wire, dash interior light switch, pin 10.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

Anyone know how to get to the security light behind the dash on a 2012 Tundra?

Thanks
