Another way to power Dash Cam
Hi All,
Just took delivery of my RDX A-Spec yesterday after trading in my '11 MDX. Needed to install the dash cam and wanted a closer power source than the fusebox.
Anyway, I did something similar on my MDX and it worked well. I could have drilled a small hole for the power cable to pass thru for a cleaner install but didn't want to be destructive.
I won't see the wire from the driver's seat anyway.
Just above the mirror, there's a cover and when you remove the cover there's a wiring harness that supplies power to the mirror for the garage opener and the auto-dimming.
The black connector has a small push tab and then pulls away from the white connector. The black connector is the mirror, the white connector gets fed from the dome light assembly.
Wiring scheme as follows:
On the Black Connector:
Black wire - Negative (-) common
Red wire - Accessory (+12v) - this is on only when the car is started or in accessory mode
Yellow wire - Constant (+12v) - always on
Green wire - weird one.. +12v whenever headlights are on, this includes when you lock/unlock the car and the headlights come on for a few seconds.
Obviously for the dash cam, I chose the Black/Red wire.

the one I got you could fit it under that plastic cover that the rear view mirror goes into, lots of space in there, one way around cutting the factory harness would be to make your own that intercepts the harness there, would need a plug that it can plug into and a plug that can plug into the factory spot and have your extra wire come out from the middle

Do you have suggestion to convert the 12V to 5V for use in the dash cam? I know blackvue is 12V but mine is 5V.
Will the extra power drain to the wire cause problem? It's probably pulling at least 5-10W.

Personally, I do not like tapping into the mirror as you lose a KEY feature of all dash cams...PARKING MODE. I installed mine without drilling any holes for any wiring to pass through and mine is mounted in a similar situation. Mine goes straight to a Power Magic Pro for Parking Mode operation and then into the fuse panel using fuse taps. Look at the dash cam thread and you will see a few installs including mine.
Yes, this is another way but it is NOT the best or preferred method for a dash cam to receive power. Most incidents happen when a car is left parked and unattended.

noob question here...what exactly is OP suggesting? Would I need to cut/splice wires for this install? Not sure I follow from schematics explanation -> installed dashcam.

i see you said you use fuse tapa from amazon, but they have a variety of different options, can you please add a link to the ones you purchased?
thanks

Hi, no I didn't use the taps. I'm a believer of splicing and soldering. So I just stripped the I insulation away wrapped the additional wire around the stripped area and soldered.
It's the most secure way.
