Parking sensor wiring cut !

i have a w207 e class coupe. The front parking sensor loom was cut during an accident. The harness was also damaged so cannot just connect the 2 ends.
On one end i have 16 wires (towards the parking sensor side) and on the other side has 14 wires.
i have matched up 14 wires according to the same colour but i have 2 left which seem to not have connection on the other side of the harness.
Does any one know /have a wiring diagram to show how many wires are in the loom ? Am guessing they might join into another wire somewhere along the circuit.
i have the 2 red lights showing on the parking indicator but no active response from the sensors.
Any ideas
