Dash cam power tap from rear view mirror?

I think there are many threads about hot wiring a dash cam here in PriusChat, I didnt do a search but here's a link from SiennaChat LOL

There is constant power at the vanity light in the headliner. There is switched and constant power in the overhead console - just meter out the harness plug for the little overhead console. I stole constant power from the map light for the Homelink buttons in the rear-view mirror and switched power from the overhead for my auto-darkening in the rear-view mirror.

 

Tim,

Do you have any more info on what you did with the Homelink buttons and auto-darkening mirror?

 

I pulled the overhead console and tapped into its harness after testing for constant and switched power. Tight squeeze, but not difficult

LG-H810 ?

 

OK, thanks. What was the advantage to switching the auto-darkening mirror to constant power?

 

The mirror got switched power

LG-H810 ?

 

Thank you! I will not route a wire around or poke around anywhere near the airbags. Using switched power reduces the risk of draining the 12v battery when parked a long time. What's the current limitation on the mirror? Do you need all 3 parts shown in the link?

 

First of all, sorry I don’t know the current/amperage limit of the power/homelink mirror, I just tapped into it and assumed my dashcam won’t cause a problem or blowin fuses.

On the link I posted, I followed the instructuon to install dashcam in my Sienna (hints why linked from SiennaChat), but since this USB cable/tapping pin isn’t available any more

, I bought this instead -

and asked a friend of mine to solder paper clips to the ends as tapping pins, so I can just push the pins into my homelink mirror circuit for switched power and ground. Been running this setup on my Sienna for 9 months and no problem at all.
