Something odd the obd says pump temp is 300 F.
Pump runs fine when buttons pressed.

The front latch is connected by a harness of its own, lying in parrallel to the roof hydraulic harness on the right.
At the CTM, there are 2 connectors:
1) a 2-pole for the latch motor, directly connected to the CTM
2) a 5-pole small flat plug next to the black 41-pole CTM plug, that connects the two microswitches from the latch motor
Both are working the same way as the typical roof switches: 560 ohms as well as 2.7k ohms. You should check it.

I'm assuming the microswitch in the windshield frame top, tells the motor to rotate cam to latch.
The cam microswitches seem to work, rear shell 2 moves up or down when i press the switches manually.
I need to check if the windshield switch is operating on the obd reader.

Umpfh, I've seen already a windshield MS, that was flooded and destroyed by WD40. Hopefully yours is ok.

Today's plan is pull plug off the lock motor and drive it by battery to the locked position.

From searching online it seems 0.14 mm2 is easily sourced, would that be ok to use?

I wouldn't suggest 0.14 mm2 in an area with heavy movements. That is very tiny and difficult to work with, as it has a higher risk to just tear it.
0.25 mm2 is a minimum in the cars. The OEM take stiffer 0.35 mm2 to 0.50 mm2 for the sensor wires.
I use these ones:

I don’t need them yet but with the Zed 11 years old I fear the worst so planning ahead and getting stocked up.

Seen LiFy wire, goes for about £6 metre.
So car roof all sorted now.
Sometimes just chase your tail.
I did at one point pull the Hall sensor and test it.
It was cracked but worked fine.
I tested with 9volt battery in series with multimeter set to 200ma.
Results. I just placed a craft blade on it, any steel will do.
So i soldered it minus the connector direct to wires and refitted.
So having about 3 different coloured wires on one length.......i ended up getting them crossed
No matter how careful i was i still managed to f u.
(Bit weird i was working next to where we buried the works cat, i asked, "Ollie where have i gone wrong," i imaged he would meow" Crossed wires?")
But all working now.
I also fitted a wire from the boot to cabin to remote release the boot when roof is half open. I intercepted the grey/green wire (goes to the boot unlock solenoid), popped in a diode, didn't want any power i added going back to any module.
Then passed wire through to cabin.
I can now apply 12volt to wire, plus ground and open the boot at any point in roof operation.
Might even wire it to the cabin boot release button i bought but never wired.

The 50m roles LIFY 0.25 mm² from CONRAD cost about 10€ per colour. That is 0,20€ / 20ct per meter.
Well done, congratulations.
As already written, none of the cracked, rusty and non-working hall sensors I've already replaced had an electrical issue. Nothing can be measured, as the magnetic field is disturbed, which lead to timing failures.

Well i measured the current change on the bench and did the same in situ using the ram to trigger sensor.

Yes I see. But so far I'm not sure what's up with the rusty and/or cracked HS.
The range of failure modes on these HS is varied: from short bongs with interrupted moves up to main columns crashing into a closed trunk lid. I suspect that the current change occurs too early or too late due to a disturbed magnetic field. One of the last mysteries of this roof.
