So I just spent the better part of about 90 minutes getting my VIOFO A129 Duo hardwired to my 2019 Clarity. Thanks to some helpful folks here and on the r/Clarity subreddit I was able to get it done without a hitch. I wanted to share the experience with you all in case this might make someone’s life easier. First thing’s first, if you’ve made no other electrical changes to the car, you can use the 3-wire hardwire kit for the A129 without piggybacking on any active fuses. You’ll want to use slots 2 (ACC wire) and 18 (BATTERY wire) in the driver’s side footwell (under the steering column to the left) which are both empty. In addition to the 3-wire hardwire kit, you’ll also need 2 fuse taps (this is the pack I ordered: https://www.amazon.ca/dp/B01J9GTL6O) to connect to the hardwire kit leads (VIOFO also sells fuse taps so if you’d prefer to get theirs, you can). Once you’ve connected the taps to the leads (use a crimping tool or a pair of needle nose pliers to pinch the taps onto the leads), insert one of the included fuses into the top slot in the tap. With the tap’s pins pointing down and the fuse slots facing you, insert the fuse in the top slot (see below). Now it’s time to connect everything. The tricky part for me was getting to the ground post. Sorry I didn’t get a good picture of it but if you’re looking at your fuse box, you can’t miss it. It’s in behind and just below with about 342 ground wires already attached to it. It’s circled in yellow in the next picture which also shows the fuse taps connected to the fuse box. You’ll need to loosen the bolt a little so you can slide the ground wire pins around the post. Tighten it up and you’re in business. I found that I had to pry the plastic plate with the fuse diagram on it off to give me enough room to work. This cover takes some dedication to get off but it does come off and goes back on surprisingly easily. The nice thing about doing this is that it makes tucking the hardwire kit’s fuse wires behind it much easier. Once you have the fuse taps plugged into their respective slots and your ground wire secure, tuck the coloured wires into the space below the fuse box (where they’ll be covered by the plastic cover). Pull the in-line low voltage protection box out toward the driver’s side door jam before replacing the plastic cover. Run it out the left side of the plastic cover not over the top of it. You should now have everything in the footwell tidied up and a small plastic switch box and long USB cable dangling out your driver’s side door. See below for placement of the low voltage protection box. It fits PERFECTLY in this space, leaves the switch easily accessible if you want to change the setting (say, if you know you’re going to be parking your car for an extended period of time and want to protect your 12V battery), and this orientation has the high setting at the top and low setting at the bottom. I found at this stage it was easier to work backward from the camera because the slack in the USB cable can be more easily tucked into the frame of the car in the door jam than into the headliner. You’ll need to pull off the rubber door trim and you’ll see a couple of open spaces where you can tuck the excess cable before sealing it back up. From your camera, run the cable along the edge of the headliner, tucking it in, until you get to the windshield side beam. With a little force you can press the cable into the seam between the hard plastic beam and the headliner. Then, with the door seal pulled off, you can run the cable down the door jam and feed the excess slack into the spaces down edge until it’s all tucked away. Replace the door seal strip and make sure the low voltage box is oriented as you see it in the pictures and you’re all set. If you have any questions I’m happy to provide more detail on the steps I took.
