Here's the plug designations per the EWD
Seat heater control LH- b2 White
Seat heater control RH- a2 White
Seat heater switch LH - f2 Black
Seat heater switch RH - f3 Black
The lower case letters seem to be an important part of the designation because some plugs are
UPPER CASE, some are all lower case.
Hope this helps you out - I have no idea where you can get these from!
Anyway I will keep looking. Thanks for everyone's help. Does anyone know where I can get the 2011 wiring manual.
I have a 2011 and have used the 2010 EWD religiously for lots of projects (see my build thread). I am 99.9% sure the seat heaters are the same... Sure you have the right controller?
Hi-
I realize this is an old posting, but were you ever able to find the correct wiring harness for the seat heater sub controllers? I have everything to install OEM Toyota heated seats in my 2012 Trail except for the harness that actually powers that controller.
Any luck or info you could share on that part number?
It would be great appreciated. Thank you.
I plan to do a write up when I'm done with all the details on the modification.
