I have this set up for dash cam with my '15 ES: tapping mirror power with adapter like this.

Anyone done/know if same can be done with '13 RX (450h) ?

 

Following.

 

I purchased a similar adapter from trailgridpro.com. They primarily specialize in Toyota Tacoma aftermarket parts. I explained my situation with the representative and was assured if the part didn’t fit, they offer a liberal return period.

I installed the adapter and both my rearview mirror and new dash cam work seamlessly.

2010 RX350 AWD

 

can you please provide link to the item you bought ?

 

says Lexus RX 2007-2025 ... I sent them an email as they suggest, have not yet received any response. I am tempted to just order it. If it doesn't work, return it.

 

I believe this is the adapter:

Remove the wiring cover from the mirror, disconnect the power source and count the number of pins in the harness. Order the adapter with the same amount of pins.

You can call Trail Grid Pro at 301-835-9100.

I hope this helps!

 

In case any one tries to use voltmeter to check out voltage ... word of caution ... the rear view mirror plug into the upper console has a loop that completes the circuit back to the upper console.

In 450H for sure there are some thin voltage wires [350 may have the same]. So not only voltage, but also the current load has to be kept in mind before you tap in.

Thanks very much for the link! I ordered a 14-pin adapter for my 2010 RX350. Bought a dash cam from Amazon. Everything works! I just have one complaint, the power to the mirror ONLY turns on when the engine is on, not when the key is in accessory position. It take time downloading the videos from the dash cam to the phone, and I have to keep the engine running the whole time . I can see why Lexus decided to do it this way, just not optimal for dash cam.
