I am hardwiring my Radar detector into the fuse box. If anyone else has done this, what number fuse slot did you use, and which fuse box? most of the ones I'm trying to use are always energized. I am looking for one that is HOT only when the ignition is on. Thank you

 

there is no such fuse at the front. Your best bet is to tap into the cigarette lighter.

it’s the 7.5amp fuse on the right column of fuses, not in the left column set

Panel located on drivers side to the left of the light switches.

I have my V1 gen 2 hooked up with a hardwire kit - works perfect.

 

fuse 218

 

I would not recommend putting it on 218 as that is the airbag systems. Try 217 (ETC Toll Collection system).

 

I have a 2019 C63s (facelift) coupe. I initially tried to run the wires down the driver side A-pillar and tap into the fuse box on the driver side of the dash without success - they were always receiving power. I ended up running the power wire to the trunk and tapping into the trunk fuses for this purpose. It honestly only took another 10 minutes or so to run the wire to the trunk. I used a fuse-tapper.

 

I gave up with the fuse boxes on the passenger and drivers side and tapped into the 12 volt outlet on the passenger side of the footwell on the console side. It should be an easy wire run up the side pillar. There is a nice ground post by the passenger side fuse box that I'm going to use. I'm going to mount the radar detector to the windshield with black high temp double sided tape from 3-M. I will be using part of a Blendmount bracket along with a bracket I fabricated from aluminum that will allow me to mount directly to the windshield. I will post some pictures when complete. It should be a very clean and somewhat stealth like look.

 

my 217 only has a single side. Are you suggesting I put the wire directly in the slot without a fuse? I could also get a fuse tap to put in there, but the other end would be open.

 

That blank spot is the one to use, it's switched power. If you plug it into that slot it will work, you can use an add a fuse to secure it.

 

here's what you need

I am ignorant of this wiring with fuses - would the wire coming off of this fuse holder be used to power the radar detector, and then you just have to find a ground?

 

Correct, there is a large bolt by the door you can use for ground and you're all set.
