Hi and thanks for using 2CarPros.com.
I just looked at the schematic. I see no brown or red. However, something may have been added. All power supply wires to the back up lamps are green.
First, check to see if the fuses are good. There are two related to the circuit, a 15 amp back up fuse and a 25 amp back up lamp fuse. Both fuses are located in the under hood fuse block.
Next, since you reinstalled the utility body, there is a good chance you pinched a wire (which may have resulted in a blown fuse.) If you find fuses which are bad and they blow each time they are reinstalled, you pinched a wire.
I have attached the wiring schematic for you to follow. You indicate "little knowledge" in the heading, so I would also like to supply a few links. These links discuss how to check wiring, use a test light, and use a volt/multi meter.

The schematic had to be broken into two separate pictures for me to get the entire thing. Check the things I mentioned and let me know what you find. If you run into trouble, let me know.
Take care,
Joe
