Success! Instructions and Amazon.com: Hydencamm Upgraded Mirror Plug Wire Tap Radar Detector Hardwire Power Cord Kit 16" suggested above worked with the exception of where I had to tap into to get power to the unit. Turns out I reverted back to the wire colors I used for my L320 RRS - black to black and red to green/white. Not sure if this is exact model specific, or if possibly the mirror tap cable is wired incorrectly into the RJ11 (I'd bet on that). Nevertheless the wire is in fact super thin when passed between plastic and glass, and I have almost no wire showing with the Valentine 1 Gen 2 mounted high on the driver side to keep it in the solar reflective cutout.

I started by removing the mirror shroud. It should be noted that there is a tiny recess about halfway up the middle of the shroud that can fit the flat edge of an eyeglass screwdriver to pry the plastic pieces apart without damaging the finish. Once separated, they pull out sideways, and there is a small clip towards the top of the plastic that needs to be released by pulling the plastic parts to the left and right.

Once at this stage, I would recommend gently pulling outward on the bottom edge of the plastic shield above the mirror. This moves it away from the windshield just enough to push the tap wire underneath to hide it. Leave about 2 inches of the wire out adjacent to the radar detector position (the RJ11 end). the rest can be pulled through to where the mirror tap goes.

As above, release the grey plug, and, in my case, wire black to black and red to green/white. Voila!

Pictures below. Thanks to all for the great advice!

 

Great info. I am looking forward to hardwiring using mirror tap but do these instructions also apply to 2024 or 2025MY Sport? I presume so but wanted to check.

Thanks

 

How did you hardwrie it?

 

I need some assistance here I have tried mirror taping to my RR2025 and don’t seem to find the right combo with the colors. Every thread I’ve read has a different color. It has two browns, one orange and red, one brown and green, one black and one blue white cable.

Will add pictures for context.

 

Update ordered the circuit tester: black cable connects to brown (ground) and red cable connects to black (12v). Without the circuit tester I would have never thought this would happen.

 

I just did this, and experienced the same as you. I do know my wires were different colored than what you have pictured for my 2023. There were a couple wires that had power for a bit, but one eventually would go out with the ignition off. I used an electric circuit tester to problem solve: Circuit Tester

Sorry, I did not take any pictures, and I really do not want to open the bracket up again risking a broken tab.

 

I’m doing this as we speak and I do not have a green white on my 2025 RRS SE. I have green brown and a solid brown. Any advice?

@jdc82 the way you have wired above. Does it shut off when the car is off and the internal computers shut down?

 

It’s very challenging guessing which one is the positive and negative without a circuit tester. Radar turns on the second you open the vehicle and shuts down when you turn off the vehicle and lock it. Make sure you have the taping heads well inserted the if not you won’t get any power.

 

I have a 2023 and mine were black to black and red to green/white as above and works perfect

 

I have a 2025 LWB L460, I had to go black to black and red to brown with the mirror tap.

 

Finally got around to doing this on my 2025 so thanks to this thread and those involved.

I had installed a fitcamx already so it was a little tricky but it’s still black to black and red to brown. I had two brown wires on the left, it’s the top one. The black is two over on the top row.

I used the clip attachment for the V2 into the headliner, so the passenger visor can still be used. I’ll have to test if the rear radar is compromised by the visor being in the way.
