I imagine this has come up somewhere but I haven't found the right thread.

I just bought my 2021 T4R Limited a Rexing dash cam and the additional hardwire kit. In all of the posts and videos I'm finding they have some other way of doing things. Some use an add-a-fuse connection but that seems to be the old way. The kit I have has the 15 amp fuse connected to the cable permanently and I have seen instructions to just replace a 15 amp fuse in the interior fuse box making sure to check which side is hot. There are only 3 fuses that are 15 amp in that box: Rear Washer, Rear Wiper and Hazard lights.

Who has wired this before and how?

Thanks in advance.
