I’ve been up to my elbows in wire strippers and soldering irons this week. All but three of the points on this layout are on one board so with this one almost done the rest should be fairly straightforward.
And believe it or not I have had a plan (imperfect though it is) for the wiring. The main DCC bus runs along the back of the board using blue/brown wire stripped from some twin and earth with all track feeds, also blue and brown.
Alongside the DCC bus is the common return for all the point motors with all common wires from the motors in white. Yellow is used for the point switching wires which run to a tag strip (labelled) at the front of the board. The point switches will eventually connect to that strip. With hindsight I should perhaps have put the common point return at the front so all point wires ran the same way.
The motors are all Seeps and at the moment the integral switch is used for frog polarity switching (not ideal) but in time the points will be fitted with autofrogs for that purpose and the integral switches will be used for the less critical role of controlling LEDs on the control panel.
Also at the front is a 12v DC bus pair - the intention is for this to supply a number of 1amp distribution boards currently somewhere on a boat.in the South China Sea.

Connections across the board joints will be by way of D-sub connectors, doubling up the pins where higher current demands it. Lots of soldering required to complete that little job.
Finally, I can recommend JPR Electronics, who supplied the wire and connectors. Reasonable prices and quick delivery.
