I have a 2016 IS300 F-sport. I want to mount my Escort 9500ix radar detector on the mirror and tap its power so I don't have wires hanging. Does anyone know which wires are the 12volt switched power (power turns on and off with the ignition) and which is the ground?

 

Here's a diagram I found. It looks like pin 1 at the Mirror (IG) is your ignition power and pin 2 (E) is your ground. Good luck!

 

Thx! I'll LYK if it works.

 

I'm not certain which wire is which. Here's a picture; which is the IG (switched 12v) and which is the ground?

Here ya go...

 

@Sasnuke is the BEST! That did it. Thx a what a great site this is with great members!

 

Anytime allalper.

 

Note the 2018 RX uses the same pin out.. different color wires (of course (Blue Hot, Black Ground) AND it appears (I guess) the pins are smaller (??) because the push pins on the radar detector cord will NOT push in (I had to solder directly to the wires...)
