I have the N52 with me, so at the moment I can take any measurements that do not require hooking N52 up to the car. There is no continuity from resistor ends with 12V label to ground (X10). But I have something interesting - there is continuity to ground (X10) from resistor end where you had put the switch ID labels for these two: 19 right bow lock and 26 ST compartment right cover closed. Resistance was 0.2Ohms. There is no continuity to ground for any other pins with ID labels. If I measure resistance from ID label 20 then there is resistance to ground (X10) 845 Ohms, some other have similar resistance, some have significantly higher resistance.One other resistance measurement I liked you to take is when the RST module is powered down measure between any of the resistor ends with 12V label and ground. Take this measurement when the Y connector is plugged in and also when it's unplugged. The 12V label point is the common 12V pullup voltage on all the switch input line resistors.
