So I'm trying to figure where I use the defogger wire from my Matrix 50.5:

From the install manual:
"This wire supplies a 200mA output as soon as the module begins the remote start process. The H3/1 BLUE wire can also be used to activate teh defogger trigger (latched/pulsed) 10-seconds after the remote start engages. (See the Feature Descriptions in this gude for details about programing this output"

Then in the Feature Descriptions section of the Install manual
"3-11 2nd STATUS OUTPUT NORMAL/REAR defogger LATCHED 10-MIN/PULSE: This feature will allow selection of status output or a rear defogger mode that truns on ten seconds after the vehicle has started if the vehicle interior temperature is below 55 degrees F. The defogger mode has two selections, latched or pulsed. Latched mode will only stay on for 10-minutes."

So I use this Blue/White wire, and set it to latched 10-min. Now, I'm not sure what to look for to hook this wire up to since its not listed in any of the wiring diagrams I've found on this site. And since its only 200mA I'll need to use a relay.

Anyone done this on a Titan before or kinda give me a clue on what I should look for to control this?

Thanks,
Brandon

If you have a airbag proff tester , take off the defoger control
then test wich wire output while you press the button and note if it latch or a pulse so you can programe you Blue wire the same way.

Recent vehicule only require a single pulse to enable and to disable so test it out first to prevent a climate controle module to burn

At the 40 pin connector pin 12 at the BCM yellow/black. Needs a negative pulse!

Will also trigger heated mirrors.
