it isn't part of the engine loom it's part the body wiring, where the reverse switch wires that you've had to extend there should be another 2 unused pins in that plug.
grey and a grey/blue wire, are these joined?

map fault won't stop it from turning over.
Here is the guide if you are wanting to keep the AUTO Wiring harness and Computer
Modifying Gearbox Loom. to keep auto computer. (VR only)
On the manual gearbox there are two connectors One For the reverse lights and the other for the speed sensor.
Connected to the auto shifter will be a white plug with four wires connected to it the grey and grey/black wires are for the neutral safety switch. they need to be shorted together to allow the car to start.
The other two wires on this connector are pink and green, they are the wires for the reverse lights test this yourself by touching them together and looking at the reverse lights.
To get the reverse lights working you will need some more wire to extend them to the gearbox. when you have enough length crimp a blade connector on each wire *Note they do not have to go onto the gearbox in a specific order (i had a spare loom sitting in the shed so i used the same colours to keep it factory looking.)
To get the speed sensor working you will Need 3 things.
Positive
Negative
Signal Wire to the dash.
The signal wire is the Purple/White Cable this has to be extended over to just above the ecu. where you will also find a purple/white wire on a plug leading from the computer up into the dash. this is the wire you need to cut and connect your extended wire.
For the Positive and Ground i used My spare Cigarette lighter Wiring but you could also use the wiring for the light around the auto shifter surround.
Then drill a hole through your gearshift plate and put a grommet in and run the wires through to the connectors.( it is recommended you do this while the car is still up in the air.)
No MAP fault wont stop it from turning over, it will only stop it from firing... Fix the fault that you know is there first.
