In the 7th gens, does anyone know which wire I can use to trigger the rear defrost with a remote start?

 

See this link, which states in part, "While lying on your back under the drivers side dash, look at the very top area under the dash for a 20 pin brown connector. At pin #6 there is a small yellow/black wire that goes to the rear defogger. This wire can be activated by a timed (-) output from your rs... Check all wiring with a DMM."
