What's the Ford transit mk7 reverse light switch location?

The reverse light switch on Your Ford Transit Mk7 is located on the turret on Your gearbox, just under where the gear cables are connected to it. It's held on by two small clips there. You can pick up a compatible replacement part from AutoZone, the Duralast Back-Up Light Switch DR4029, which runs about $15. It's a simple matter of disconnecting the electrical pigtail from the old one and unscrewing it, and reversing the procedure for the new one. Do note that one of the most common reasons for the reverse light to stop working is a blown bulb, so also check that before replacing the switch.
