DVR Install (A118)
I'd like to install this little DVR in front of the mirror. From what I can glean from available schematics, it appears that there is a B+ line going up into the "Tint" mirror device. The vanity and map lights are enabled full time, so they are not a reasonable candidates. I expect that the rear view mirror "Tint" function would only be energized with outboard lights and/or key On.
So if the (switched) 12vdc is available up there, it would make for a much more elegant installation. Just guessing cam draws maybe 100ma @5vdc .. haven't checked it yet. A little TO-92 regulator is good for 100ma (12vdc to 5vdc). Anybody done this yet .. can anyone verify the switched 12vdc up there? TIA

I have a dash cam mounted behind my rear view mirror and I ran a wire up from the fuse panel on the driver (left) side of the dash, up the A-pillar, across the header, and down behind the mirror. The A-pillar is easy to remove, as is the header. I my opinion, this would be easier than trying to connect power and ground to the mirror wiring, and you aren't risking messing with those electronics, especially the BPM.

Thanks for the suggestion Steve. When you say "header" I'm guessing you mean Headliner? I failed to mention .. my XK8 is a convertible .. headliner is in the top, as it were. Glad you found an elegant solution though .. also I'm guessing that your fuse-box connection was to a switched circuit, and your cam/dvr works of off 12 volts. I'll look into it .. very low current consumption .. 26ga twin-lead would work just fine .. should be easier to wrangle in there somewhere. Cheers!
I suppose if it were me and I had a 5 volt unit, I might consider wiring an actual adapter in to the fuse panel. I assume your cam came with a cigarette lighter adapter? You could hide it behind the kick panel. Just my thoughts.
