Hi, I have a 2005 C240 and I recently installed a new Sony XAV-AX1000 stereo, it's a huge improvement over the stock base stereo. I installed the radio myself using the Crutchfield pre-assembled wire harness. Super easy job, All i had to do was plug in the harness and no cutting wires. The radio has a back up camera option so, I bought a decent quality back up camera and it has 3 wires, a yellow plug that goes to the back of the radio and a power & ground wire. I'm not sure how to hook up the power and ground wires, most people splice into the tail light harness but, I'm not going to do that, that will for sure wake up electrical gremlins imo. I could install the ground wire anywhere there is clean metal to connect to so, I'm not to worried about that unless someone knows a better solution? The power wire concerns me, I want to hook into "key on" accessory power source. Does anyone have a recommendation for wiring the positive accessory on power supply? That's my biggest concern. I forget the name but, it's a license plate frame back up camera....it was over a $100 bucks. Thanks in advance

I found a ground in the trunk near the passenger side wheel well. (You need to remove part of the passenger side trunk liner to see.) I couldn't find another option for power and I spliced into the power for the backup light.. It hasn't caused a problem for over 3 years. See post #6 in this thread for more detailed information: Back up camera

This thread: Audio System Wiring also has some useful information.

I’ve had my “PTS” powered by the right reverse tail light since ~2005...no issues.
