Point Motor Wiring Looms

Currently under construction are wiring looms for Cobalt Digital IP turnout motors on now two of my modules. Cobalt point motors by DCC Concepts require a 10mm stripped bare wire for connectivity, and they recommend against tinning, even though fellow module owners have and it works.
Coincidently, the spring connectors are the same pitch (2.54mm/0.1″) as PCB header pins but the standard size is 14mm LOA, 7mm accessible with the plastic collar in place. I’d like to keep the plastic collar as this effectively makes it a plug, so easier to service. I’m just waiting for my electronic component supplier (Dear Old Dad) to confirm whether he’s got longer header pins in his stock, as I don’t really want to buy a bag of 1,000!
As these wires only carry signals from the switch to the turnout motor, I’ve deliberately avoided any of my track bus colours. The first article in the latest MERG Journal has made for some very apposite and topical reading!
