Rear Camera Wiring Issue

I have a 2011 G37x. I just removed the center console and carpeting and put it all back, but my rearview camera is now blue and most likely disconnected. Could anyone help with which wire to look for when trying to reconnect it? I have no idea what’s what.

Thanks in advance!

I'm going to guess you may have missed a wire-to-wire connector while reinstalling everything but I can't quite point to where. The camera signal and power are part of the big plug that connects to the back of the AV unit, but there are a couple "in-line" connectors on the run to the rear of the car. Maybe right behind the radio? Or maybe under the carpet? If you want to research it before you jump back in you can find your FSMs here:

Do you have any tips of what to look for in those documents? Also, I’m pretty sure I disconnected something in either the wiring/harnesses under the center console/arm rest, or in the wall left of the brake and gas petals. I did not mess with the upper center console or infotainment area.

Yeah, the books are pretty hard to wade through... The wiring path from the rear camera appears to first go to the driver's side of the trunk, then crosses over to passenger's side, runs along the floor towards the front of the car, but there is a branch that turns left and runs to the center console.

There, connector B221 (from the camera) should be connected to connector M149 (which looks like it's on the passenger's side of the floor console). Even though the connector has 12 pins, it may only have 4 wires.

I hope that's the answer!

Thank you so much! That looks like it’s definitely the answer.
