Nice write up. I am looking for a wiring diagram for a 2013 Tacoma,where did you find your diagram I am going to install a remote starter. I found on two different sites for the second starter wire one site shows -, and the other site shows the second starter shows + on the bulldog Security Diagrams. Bulldog told me it was the same as 2012 wiring. But it bothers me that the 2 site shows different -. Check it out..
Thanks for your time
