12v wire tap for Radar Detector
- Thread starter surfrasch
- Start date
Well, it stayed on all night using the red wire connection. I was going to try a test with the 12V plug but it sounds like that will get the same results.
Maybe I’ll send a tweet to Elon asking for a mode switch in the software where we can choose the mode for the 12V plug, always on or switched. Our own “Joe” mode for accessories.

Follow up, it looks like the original tap point and the 12v plug work the same, always on until the car goes completely asleep. Whenever the car wakes up, even by using the app to get a status both come back on. I guess we will just have to get used to manually turning it on and off if we don’t want it on all day like in the parking lot at work with sentry mode active. Oh well.
I called Tech Support at Blendmount as well. Got the same no answer answers for both my Porsche and Model 3. They absolutely have no understanding of the application of their products. NOT ACCEPTABLE! They need to know more about how their products are installed than anyone else. Got my Porsche working by following advice on the Porsche Forums. Tesla is next. I really want to plug in to the mirror or the back of the cameras, not the other sources of power that are much further away. Note: some detectors like the Uniden R3 have an auto shutoff feature you can enable. It will shut down after no movement in half an hour. Not terrible. You can also just shut if off manually. Of course auto on and auto off is best. So even if the power source is constant and there is no intermittent source, I will use that if I have to. Also in my opinion those Blendmount mirror taps are a great idea but grossly overpriced. Uniden sells the identical product for one third the cost. Same for the mounts. They look great. They work well but $140 ??? Thats nuts. Somebody else should jump in and take the market away from them.
Do you happen to know if that power going to the mirror is constant or intermittent? I can deal with it either way but prefer an intermittent source that is only on when the car is fully on.
Please let me know if you get this to work (either with constant or intermittent power). This is my preferred approach if it works.
Or can be used with a detector like the Uniden R3 that has the option in the configuration to shut itself off or even if you remember to power it off.
Would you please post a photo of the source of 12v constant power in the harness that feeds the nearby assembly? What possible good could the two wires feeding the mirror be without power? Is it possible that it might have power only under certain conditions?
Has anyone done the light blue wire in the door jam approach recently? [see video below]
With my 2018 Model 3 I ran a 20' cable all around and drilled a hole into the center console and use the cig lighter adapter that came with the V1. That was a giant pain in the ass. That said, it turns on and off at the right times.
Now there's a 2020 Model Y sitting in the garage. If there's an easier way to wire this thing I'm all ears. I have done an hour of research on the subject but it's not abundantly clear to me if the approach mentioned above is turning on and off properly, and with the current software.
Thanks!

The light blue wire gets power anytime the car is awake. If you want the power to switch when you enter and exit the car, you can add a relay on the center console led switch circuit. I posted some photos of this here.

Just did the blue wire install... takes maybe 15min total to do this and so far my car hasn't gone up in flames!
Made a chitty video, will share once I get it uploaded.

Don't be making fun of dirtyazz car
This video took longer to record and process than the actual install... including removing panels, tapping power source and putting it all back together again.

The lighter socket isn’t a true switched 12v source. It remains activate anytime the car is awake.

Hi, I'm not sure what that technically means. Is that a bad thing for a radar detector or for the car?
Thanks for help, appreciated as always
It means the radar detector turns on every so often as the car wakes up to check for updates, or because you checked the charging status on your phone, or your datalogger pinged it to get data, or anything else that causes the screen to light up.
It may put additional load on the 12V battery (but ... not really. But Tesla may claim as much to get out of replacing a bad 12V battery).

If I shut my Radenso Pro M radar detector off when I get out of the car, wouldn't that be ok? It wouldn't turn on until I reenter the car and physically turn the detector on.
That's basically what I do (V1G2, hardwired in. I unplug it.). There's the risk I'm comfortable with that Tesla may reneg on replacing a 12V battery, but I'll deal with that if if happens. (Their 12V charging seems to have gotten much better)

Thanks so much, Thats what I'll do if I ever see the ordered car LOL, or if they continue to strip parts and features off the 2021's I'll buy the Taycan S
