Hopefully the Mods will remove your address, you shouldn't post contact details on posts. I've sent you a personal message (PM) about the connectors.
There are quite a few diagrams showing the connections, I'm a little confused as to where the 5.2V supply is, not sure if it's one of the 5VA ones that is maybe labelled wrong. Possibly wise to check with your meter to confirm which are joined together.
The sense lines are normally used for compensating for volt drop (from the higher current supply) in the traces from the PSU to the rest of the circuits.
You could either connect separate wires at the load resistor end, or connect together at the connector end, just remember to measure the voltage at the point where they are connected.
Still need to work out how to disable the HT section.

Edit: If someone has an original manual showing the second picture of the connector diagram (above) that is clearer that would help a lot.
