2013 C300, Does anyone have an easy to access wire or know of an unused but switched by acc/key on fuse in the fuse box for hardwiring a dash cam? Don’t really want to rip half the dash apart or anything crazy so either way is fine I can buy an adapter if needed to use a fuse in the box if needed or wire it to an easy to get to spot, either way they need to be switched power and not constant. Also don’t really have access to a Dmm or test light due to living situation but want to have dash cam because insurance.

I tapped into a fuse in the rear SAM in the trunk. I used the test probe to identify the "always on" circuits.

JettaRed's recommendation is the easiest way to to tap into a fuse block and add an independently fused circuit for an accessory device. You can find these fuse taps at most auto stores for less than $10. Search the forum for additional info for installation details. Finding a switched power point is the challenging part as some circuits have delayed shutoff.
