Hello,
I want to connect a aftermarket dash cam. Please do not know which fuses on the driver's side to connect the red and yellow wire to?

You’ll need a multimeter to check them.

I plan to measure with a multimeter.
I was hoping someone had gotten ahead of me and I would know before the surgery.

If you did before I said anything then your car would probably turn into Optimus Prime and run away which would be problematic.

Optimus Prime would be good too
I've put the cams on four previous vehicles, so hopefully I can do it on the fifth. Just from the description of the fuses, it is not clear which is the constant current. Well, I won't have to measure anything. Just so that there is a constant current in this fuse box.

(sorry for my english language)

I want to wire a dashcam on the back window and tap into the fuse box in the trunk.
Any idea how to route the cable from the trunk to the interior in a tidy way?

I just installed a u1000 with radar and rear facing camera and a ivolt battery backup in my 2022 c300. If you hard wire, you must find a fuse box that has both a constant 12 volts as well as ignition switched 12 volts (only on with ignition. The fuse boxes with the 200 numbered fuses seem to all be constant 12 volts and never switched off. Since I was installing the ivolt in the trunk, I used the fuse box behind the right rear fender. There are both 12 volt continual (for red wire) and 12 volt accessory only.(for the yellow wire). I popped the air bag cover along the right windshield post then down the side and under the door opening going to the back. I think you can also go above the door, all going to the rear door panels that touch the top of the rear seats. Dropping the seats I ran the wires behind the trunk panels to the fuse box.

To tell which are constant and which are acc, take a 12 volt probe to the fuses. Some will stay on while others will follow the ignition. I then used a tap-a -fuse into an empty fuse slot about 406 or 407. This gave me the accessory. to charge the battery. with a ivolt you only need an acc connection. The yellow and red wires come from the ivolt to the u1000. If you are not using a back up battery, you can use a tap-a-fuse from that fuse box for both a constant and acc connection. I think the fuses on the right side of the box are constant power, while the left side are acc controlled.

did you do it?
