Hello all,
With my previous cars, I have added dashcams and some kind soul for the most part had mapped the fuses for always on/switched on so you could use fuse taps to make those accessories work with pretty minimal work on your own. I've not seen a comprehensive list yet in this forum (although a general consensus of fuse 3 is out there), so because I'm going to be powering my dash cam for normal and parking modes and adding my GMRS radio via fuse taps, I spent some time Saturday testing all the fuses in the interior fuse box (not the box in the engine compartment) to see which fuses indicated power when the car was off, in accessory mode, and when running. I thought I would share what I discovered.
So, here are my caveats with this (based on internet and real world experience):
Fuse taps do have a direction to them - I found this video to be helpful in explaining that. In that vein, I pulled the Micro 2 fuses listed as "Not Used" or "Not used (spare)" in my Owners Manual and tested the sides to see which side was hot. This was the results of that test (red circles are the side showing power when the fuses are pulled. Sorry this picture is too dark to see the fuse numbers. I basically flipped the owners manual on it's side and the picture then matches the orientation in the car. There are labels for the fuses on the panel.):
I did not test the Micro 3 "Not used" fuses as I do not plan to use a Micro 3 fuse tap.

So, here are my caveats with this (based on internet and real world experience):
- Always test your own fuses to confirm. Sometimes things change during build years.
- I do not know how the auto-stop/start function impacts these fuses and the performance of the items you might connect to them.
- I am not making any recommendations about what fuses to tap. My general common sense says don't use a fuse that controls a vehicle system if you can avoid it, and if you can't, either be absolutely sure you know what you're doing or pay someone who does know. The last thing you want is a vehicle system not responding or your airbags going off because you messed with the fuses and something happened.
I am not responsible for how you use this information, so as the Knight warned in Indiana Jones - choose wisely.
- I have a Big Bend trim. Build date of 6/2022.
- I did not test the fuse labeled "25"
Fuse Number | Vehicle off - Passenger door open and waited 45 minutes after the interior lights went off to test. Key was in the house. Then repeated - key was in the car but other variables the same. | Full accessory mode | Engine Running |
4, 5, 7, 10, 11, 12, 13, 14, 17, 18, 19, 20, 21, 22, 23, 24 | Powered | Powered | Powered |
1, 2, 3, 6, 8, 9, 15, 16 | No Power | Powered | Powered |
