i did my hardwire install of Valentine One in my 2011 4.6 a few weeks ago.
Hardwired into overhead light console after finding description on Amazon. the below pics are taken from the nice gentleman's amazon pics. Opened sunglasses holder- unscrewed 2 screws. pulled console down slightly. unhooked wiring harnesses and i think maybe 2 more screws that became apparent. you will see the console fits into a black plastic frame/tray that is attached to roof. also remove the black plastic cover that contains mirror power on the top center windshield.

then unplugged harness closest to passenger seat (apparently sunroof harness). using valentine's direct wire power adapter tapped into the middle red wire (switched 12v). purchased another direct wire adapter from Lowes and tapped into the black wire for ground. unplugging and replugging this harness can be a real pain (prepare yourself with alcohol). test connections at this point by turning on V1.

tucked the direct wire adapter stuff up into the roof above the passenger seat. drilled a hole in front portion of black plastic tray and ran Valentine One's power cord through it and to top center windshield. sorry i didn't take a picture. tuck wires away above as best you can then replace overhead light console by reconnecting wiring harnesses, replacing screws, etc. retest connections again. home stretch baby.
i used this mount, because it allows 3D adjustment. installed mount and ran wire- used 1 black tie wrap to hold wire close. good to go. looks similar to this now:

in regards to audi/vw falsing with V1, i have noticed a few times when i couldn't figure out source of obvious falsing and have been able to locate a newer Audi or VW near me. this happens rarely. i have been very happy with the V1 and the hardwired setup. in the next 6 months, i plan to purchase and install Laser interceptor dual.
Thank you for bringing this old thread bad to life. Found lot of information and just finished hard wiring my old escort x50 blue to my genesis via rear view mirror.
