Would anyone have the original uses noted for the four-wire connection between the Nikki & Frank S loco and tender please?

Assuming my old sketch is correct, marked 20261 tender
Top Motor Green via DIP sw
2 Common, to PU Brown
3 PU & rear plug White
Bottom DIP sw to rear light
Phil, I would most certainly suggest testing out the connections with a Meter as well. Just in case!

In theory, I should be able to do all I need by attacking the tender behind!
Had my one of these to bits, loco and tender. A weird system where the tender picks up power, sends it to a circuit board in the loco which sends it back to the motor in the tender along with the loco pickup and motor.
I have a bald patch just because of this loco
Yes, I had the same perplexation with the Frank S version. I assumed the tender was broken because it wouldn't run independently. Spent a long time trying to troubleshoot it before figuring out the weird interaction with the loco. I was intending to put decoders in them anyway which I eventually did. 55021s in both. Pretty easy and now both can run independently as expected.Had my one of these to bits, loco and tender.

Didn't the original analogue Frank S/Nikki&Frank S models have some circuitry in them which reduced the tender's speed slightly to compensate for its tendency to try to push the loco along? I assume that is the reason for the "odd" wiring between the two....?
At some point I will need to look at chipping the NOS green one I managed to find a couple of years back - I haven't had one apart before, since my blue N&F came to me with two Massoth decoders installed by a previous owner, and my black one has LGB factory-installed DCC and sound.
