Assuming everything is back to it's original place and you didn't inadvertently sever a factory-made connection, have you confirmed the fuse on that circuit didn't blow at some point while you were making your modifications?
That's a good point. If you were poking around with a meter trying to determine hot and ground, or inadvertently pushed your hot and ground pins for the device in the wrong places, you may have blown a fuse.
Both of you get today's "Genius Award"! While I did get some voltage out of my cheapo meter, that was after several erroneous meter settings. I also wiggled wires clipping an unneeded wire tie I'd used in the old arrangement. So, I did check fuse C3 on the passenger side fuse box and sure enough, holding it up to the light, it was severed. So I ran up to the auto parts store (running in the sense that I drove my Subby Outback there) and bought a pack of 5A fuses. Came back, pinned my wire to the pigtail, and replaced the fuse. Ta da!!! Let there be light!

Thanks for the help and pointers!

Thanks @HooosierDaddy! In case this fails, I'd love to hear how you ran wire to the fuse panel. It looks like there is a tunnel from the overhead compartment in the direction of the windshield pillar. Did you use that?

LOL... that would have required me to remove something!

Used a panel tool to pull the edge of the head liner open just enough to tuck the wire in and over to the A-Pillar.
Popped the top of the A-Pillar open with same tool, just enough to get the wire from the headliner into the A-Pillar. From there, use the panel tool to gently open the edge under the rubber seal to route the wire down through A-Pillar to the small middle trim piece. The only panel I physically removed was the bottom trim panel covering the fuse block. This one is tricky in getting off because you first need to pop the two "industrial grade" velcro connectors at the forward position of the panel. Centered vertically and roughly an inch back from where the carpet runs under this trim piece.

The small mid-trim piece between the A-Pillar and the fuse block trim panel needs to be released at its bottom, which is a shared body clip for the top of fuse block panel (kind of a two for one deal). With the velcro and top clip loose pull the lower panel back while rotating (pull back and from viewpoint of outside the vehicle facing the right door, rotate clockwise). Once removed the fuse block area is wide open and you can make your connections. I don't know, I feel like written instructions are difficult to convey for this lower panel. Once you do it you'll be like... Oh, now I get it!

I should have my blend mount today, maybe when I install that I can make a video of the process. No promises though... I might need to take a nap instead!

Don't be poking too much fun after I share my kindergarten pictures of how to route the wires. I really didn't want to do it all again so hopefully you can use this.
I used a standard Add A Circuit Fuse Tap in the passenger fuse block. Row D - Column 6 is the empty slot I used. Its for vented seats which I obviously don't have, but there are plenty of empty slots to chose from.

Well done @HooosierDaddy!! I was kind of amused (although appreciative) of the written instructions, but I know what you mean about how things become clearer as you try to do them. These photos really do help. Just saved the page (with pix) for future reference).

I accept the “Genius Award” on behalf of my parents, and many mentors and teachers. In all fairness though, loss of power on a properly fused circuit can really only be due to one of two things. A failed power supply, or an open circuit. Clearly the battery hadn’t failed, so yours could only be an open circuit. That left just the connections you fiddled with, or the fuse.

I love logic, although I fail to possess its powers at times. The sad thing is that one of the first lessons I learned helping an older next door neighbor working on his 1961 Ford Galaxy was, "Check the cheapest thing in a series first!" In that case, as simple as cars were then, the car wouldn't start. The series was battery, relay, starter motor. The relay was less than $1, and sure enough, that was the problem.

Oh, and a correction: brown is negative and black/red is positive to power my dash cam.

Good paradigm to follow!

I'm not a fan of radar detectors... but it saved me several times on our trip to the Dragon. That V1 can really reach out for advanced warning, provided there's traffic ahead to produce advanced warning.

Quick question, how do you safely remove the overhead panel that is removed in the first picture in the thread (the one where the overhead lights are)? Does it just pop off or is there a specific way to remove it?

I didn't tap in there, my wire tucks in the head liner and makes it's way down the a pillar. But yes it does just pop off

There are four metal clips that hold it in. You can use an upholstery tool, but I just took an old credit card and stuck it in pushing the clip in and then just pulling the card down until it pops. Then move to the other corner and do the same. Do it from the interior side (with lights).

Pull carpet down from upper right hand corner, you find a nut towards the front of foot well at the floor attaching a white plastic bracket for the fuse block. Back the nut off, insert the ground ring and reinstall.

I will be installing a Blendmount and the new Escort Max Cam 360C when my 718 Spyder arrives at the end of the year. Think I'm going to wire it from the mirror power and use the Brown negative and Black/Red positive connections.

Does anybody know if the non auto-dimming mirror has the same colored power leads? Brown negative and Black/Red possitive?
