F348 TB and GTB Mousetrack Seatbelt Wiring

Just trying to resolve the wiring for the mousetrack seatbelt wiring and came across some unexpected wires.

e.g. Three wires going to each diagonal belt reel. I believe there is a locking solenoid in the belts, but why would this need 3 wires?

I don't have the driver's manual for these cars or access to these cars, so I'm not completely familiar with the finer operational details and these type belts are not mentioned in the workshop manuals which are available to me.

The official Ferrari wiring diagram stops at the 9-pin connector under the seat and no wiring is shown for the mousetrack. Looking at online photos of the mousetrack assembly, on the GTB/GTS, 6 used wires at the plug become 10 wires at the various sub-components:

Bi-directional motor (2 wires, red and black)
Backup receptacle microswitch (2 wires, both green)
Sensor at end of track under dashboard (2 wires - blue and black)
Mouse "home" position (4 wires??? Not sure of the colours... green, black, orange, brown?)

Are there two microswitches inside the seat belt home position? Perhaps one for position reporting for motor control and one for seat belt light extinguishing? There doesn't seem to be any wiring in the lap belt.

There are so many wires, even if I, in theory, splice all the earth wires together. I still seem to have one wire going nowhere.

Has anyone looked at this issue before or might have an old harness hanging about?

The TB and TS wiring may resolve itself after I have figured out the GTB/GTS wiring.

Thanks.

 

Thanks, Ernie.
I'm just trying to demystify the system. In some cases there may be easy fixes. Unfortunately, the system seems somewhat counter-intuitive.

Here's a photo of the seatbelt reel showing three wires.

Here's my latest attempt at a diagram. The question marks show the unknown wiring.

I'm guessing the normal positions of the microswitches, but they may be wrong.
