Correct, minor trimming to enlarge the opening.

Good comments and great write up @Bluesky 07 … I’m curious any reason why you didn’t use the ‘add a circuit fuse TAP’?

If I did use the ‘add a circuit fuse TAP’ what fuse would you recommend I tap into?

Also I’m wondering if anyone has run the port into the inside of the arm rest compartment? Only because I like the thought of keeping the wires hidden. If I went this route it might make for an easier install if I went with the socket mount style like this one and just drilled the right size hole.

I’d love to get some more thoughts on this? Any problems with this route or with the ‘add a circuit fuse’ route other than it being a little more complicated install?

Thanks for your kind words. Glad to repay a fraction of the priceless help and advice this forum and others have provided through the years.

I tapped the OEM power socket b/c I didn't see any advantage to running wires for an Add-a-Circuit given I didn't plan to use the socket often, if at all, once the USB ports were available. Candidly, I'm not sure whether it's preferable or necessary to use an Add-a-Circuit if you do plan to use both the socket and the new USB ports. While I would have gone that route to be on the safe side had I planned to use the socket regularly, I've never had an issue on the few occasions where both were in use.

As to which fuse to use, there are many better sources for electrical system information that I and hopefully one of them will chime in. FWIW, I likely would have added it to either the fuse for the OEM socket (would that defeat the purpose though?) or the radio/entertainment system.

I agree that the round style you linked to would be easier to install inside the console if you choose that route.

Hope whichever way you go works out well.
