I decided to keep my Radar lower on the dash - as cops generally aim towards your bumper/license plate for an accurate "read" (License Plates and Chrome Bumpers = Fantastic reflectors!

). Mounting a radar detector "way up there" on the rear-view mirror in a high 4x4 vehicle can negate Laser detection (and can lower K/Ka sensitivity a little).
I also believe the radar is well out of the way WRT driver visibility. It covers part of my hood view - and doesn't affect ANY of the road/traffic visibility where it's currentrly located - yet it is easily visible and grabs my attention when "alerting". I also avoided the interference/attenuation from the dark-area of the windshield that surrounds the rear-view mirror in my '13 T4R (not sure if older 5th Gen's have those little "dots" around the rear-view mirror - but those will attenuate Radar and BLOCK Laser detection!).
I initially hard-wired my Escort 8500 x50 by passing the wire through my T4R SR5's unused auto-headlight sensor at the center of the dash (drilled a hole in it), but I just swapped to a slicker install where the radar wire comes in from the defroster vents (the wire is less visible - runs a shorter distance until it disappears into the dash).
Then, I just received the Escort "Hardwire Smart Cord". I gutted the small plastic pod it came in and installed the "Mute" button right below the 4WD-Selector knob for easy-access (physically reaching up to the Radar on the dash to hit the "Mute" button is awkward). I didn't need to see the LED's on the remote-mute button (Radar is in plain view), so I only allotted for the physical Mute button itself (LED's are still on the PCB, I just didn't drill any holes for them to shine through). My eyes are on the windshield/dash when driving anyways - so the Power and "Alert" LED's on the remote-pod in the console wouldn't be of much use anyways.
I used a similar "Mini/ATM" Fuse Tap to get into my fuse-box (obviously means removing the stock plastic fuse-box cover). I used one of those "ATM Add-a-Circuit" fuse taps for the reverse trigger for my Alpine INA-W910 as well (our T4R's reverse fuse only sends +12V when shifted into reverse! - Makes for a perfect reverse-camera +12V trigger!).

The hole I drilled in the console was pretty friggin' ugly - so I cut-up the Escort's "Smart Cord" label, and used the "Mute" button sticker to cover up the piss-poor hole I drilled

A little ghetto - but MUCH better than revealing the piss-poor hole I drilled...
Works very well IMNSHO. I used a small piece of rubber I trimmed and glued to the bottom of the Radar to support the Radar on the dash. The rear of the radar is supported by the windshield (suction cup mount), and the front rests on the dash (via the rubber "bumper"). This results in a completely stable mount - the Radar doesn't bounce/jump AT ALL!!! I can't stand when my Radar is bouncing around on the windshield mount!!!! :lasercannon:
Merry X-Mas Y'all! :cowboy:
