Hello, I have a 2014 F150 and I would like to add a fuse for my air compressor and CB radio relay signal. I ordered a low profile add-a-fuse on Amazon and it doesn't go all the way in. Has anyone found a add-a-fuse that fits? I saw a Ford type add-a-fuse on Aliexpress (it says ford iko blade) does it fit? I already have a pin for now and the contact isn't ideal for off-roading.

 

You don't need to use the low profile fuses or add-a-taps, a standard mini fuse style add a tap is perfectly fine. And in a pinch if you blow a fuse and don't have low-pros handy, but have mini fuses they are the same in every way except length. And the fuse cover closes over them with no issue.
HOWEVER, with that said, at least with the CB it is always best to run the wires directly to the battery to prevent noise interference. Just make sure you add a fuse to the wire as close to the power source.
