Oh. Well, sorry about the earlier bum steer, then. :(
Seems we'll have to look at the diagram.
Bridge the blue-red wire and the black wire at connector A, thereby bypassing the reverse light switch.
With the ignition turned on (position 3), both reverse lights should work.
If not, check for
- a blown fuse
- damage to the black wire running from Connector B to the rear of the car
- open circuit or damage to the black wire between connectors A and B
- 12V at the blue-red wire at Connector A, when the ignition is switched on.
Remove the bridge at connector A and reconnect the switch (70).
If the reverse lights don't work when reverse is engaged, the switch (70) is faulty.
