First plug in only one of the quadrupus cables, find out what coil it corresponds to according to screen, then plug in 2nd cable, don't test already-determined cable, but all other 3, find what cable it corresponds to according to the screen. Repeat for other 2 cables.
TT2, confirmation:
C = LL, not UR, not UL, not LR
D = UL, not UR, not LR
A = LR, not UR
B = UR

After confirming that the correct quadrupus cables were plugged in to the correct coils, I suspected that our problems could be coming from a (or some) magnet(s) touching the inside of the OSEM. We tested this a little bit, with the goal of finding the range of values where no magnets are touching.
All matrix values are either +1000 or -1000, so, with an example pitch slider value :
PIT YAW
Pit slider | 1000 1000 | ---> -22000 UL
-22.2 | -1000 1000 | ---> +22000 LL
Yaw slider | 1000 -1000 | ---> -22000 UR
0 | -1000 -1000 | ---> +22000 LR
Trying some values for pitch, keeping yaw constant:
0 yaw, Pitch bias = 5 -> UR is touching on left side of its osem.
0 yaw, Pitch 0, UR is touching left side.
0 yaw, -1.2 pitch, UR just came off from touching left side. More neg from here should be non-touching. all others are fine.
0 yaw, -32.2 pitch, LR not quite touching right side of osem, but is close (much less than 1mm clearance). UR fine. all others fine.
0 yaw, -22.2 pitch, all 4 are fine.
Trying some yaw values, keeping pitch constant:
1. -22.2 pitch, -32 yaw, LR touching. UR touching.
2. -22.2 pitch, -12 yaw, LR barely not touching, UR still touching.
3. -22.2 pitch, 0 yaw, UR still touching.
4. -22.2 pitch, 16 UR barely not touching.
5. -22.2 pitch, 32, none touching.
6. -22.2 pitch, 12, UR close, not touching.
7. -22.2 pitch, 0, UR touching.
8. -22.2 pitch, 32 (or 30?) UR came off.
9. -22.2 pitch, -25, UR close
10. -22.2 pitch, -32 UR touching.
11. -22.2 pitch, -4 UR not touching.
12. -22.2 pitch, 0 yaw, UR not touching.
Here is a graphical semi-representation for the yaw data:
