Lets see if this helps and my drawings match your car.

Looks like a 9 pin connector goes to the starter/lock out switch.

5 of the pins go to your gear indicators P,N,D,3,2

2 pins are switched for backup lights. (switches power to pin 86 of the relay coil)
Looks like one wire is grey/yellow going to pin 86 or the backup light relay
The other lead is yellow/red which might be the hot lead to this switch & Gear indicators.

2 pins are for another switch. (lock out for starter)

So do your gear indicator lights work as this look like the same power lead going to the switch for the back up relay.
