: Wiring instructions for radar detector hardwire

So, searched around a bit here, but it seems GM changed some wiring colors somewhere along the way since '09?

Anyway, just finished up hardwiring an Escort 9500xi and wanted to post a quite write up for others. Used the direct hardware cable from Escort (I live just a few miles from the factory/HQ). Was a lot easier than many other of my cars I've done.

This won't be a step-by-step since you should have some modicum of skill before you try at all, just wanted to let you know which "color" wire and ground option to save you some time.

Pulled apart the mirror plastic housing and entire overhead console. Most 12V pos were always on (lights) or relays. Only ignition/accessory on I found was the DARK GREEN wire on the smaller connector under the plastic mirror housing. Note there are two snap connectors under the mirror housing - you want the smaller one. There are 4 (or 5) wires in the small connector and there is a light green one - tap the DARK green one. There were no switchable hots in the overhead console surprisingly.

Not many options for grounding either so I drilled a small hole in the "roof" under the console. There is a raised "brace" type area you can drill (don't drill in the thin section!) and there is plenty of room for a small sheetmetal screw and it worked very well. I did not need to scrape any paint off for a good ground. Tucked extra wire under the headliner under the visor. Works great!

Hope this helps some!

yeah it was a Pain to wire my V1 system because there are no hot wires or switched laying all over the car like in a normal car.

I pulled off the side panel on the driver's side dash and found power and a ground for the direct wire smartcord. It was pretty easy to srun the detector cord up the windshield pillar and then across the window where I mounted the detector just below the sun visor. Then ran the smartcord switch under the dash and then under the center console where I mounted it along the side of console. Very neat install.
