you shouldn't need to run any wires to the back of the car since you're using the wireless transmitter. The wireless transmitter has two functions (a receiver and a transmitter) and you should be able to just follow these procedures:

From the Trunk
1) Wire the black wire from the camera to any ground
2) Wire the red wire from the camera to the wireless transmitter (sender side)
3) Wire the wireless transmitter (sender side) power wire to the reverse lights

From the Cabin
1) Wire the red wire from the wireless transmitter (receiver side) to the fuse box
2) Wire the black wire from the wireless transmitter (receiver side) to any ground
3) Plug in the yellow RCA cable from the wireless transmitter (receiver side) to your iDrive interface input
