in the front power distribution box (Fuse box on engine bay), just besides the fuses and the LKM (Light control module). If you pull up the CCM (Clearly marked) you will see at the bottom of the box two connectors, one is green the other blue. Your problem will be to access those connectors keeping the CCM connected. Guess you can do some disassembly so to have the CCM out of the box but with both connectors plugged.
