w212 facelift tail light wiring

I bought a replacement taillight off pelican parts because of the typical faulty left hand light.

The new light part number is A2129061303 (4 wire)

The old light part number is A2129060703 (5 wire)

The conectors between these two lights are slightly different and the new one wont plug into the wiring harness due to the offset tang being in a different spot.

Does anyone have access to wiring diagrams that could help me out here?

Can I just swap the plugs and keep the wires in the same positions and assume the extra wire was an extra ground or has something totally changed on these lights?

I do not want to send these back as it will cost to much I want to figure the wiring out. Im in NZ and the car is a japanese import.
