I have a few extra wires that aren’t connected to anything and I’d like to know what they go to. I believe that one of them became disconnected when I pulled the batteries to check the water levels but I don’t want to randomly plug stuff in and fry something. The red wire is in the loom that goes to the rear lights and they all appear to be working, the other wires are blue with yellow stripe and yellow. Does anyone know what these 3 wires go to? 
Thanks Derrick
My ’07 E2 has the blue/yellow and a red/yellow in same location that are un-used( not connected to anything)
The red is connected to a blue/red that is in the large loom that goes forward
One may go to the rear license plate light, and its ground.
