Many thanks @Cv6benplus and @Alemito on your fault diagnosis.

Turns out there are multiple plugs in the module box in the engine bay that match the colour coding as well as available pin locations for this install.

Id plugged mine into the upper of the 2 plugs in sync, you actually need to plug into the standalone multiplug above the main positive feed. The BMW instructions the dealer gave me didnt specifically go into the images of said plug arangement and just shows the wiring diagram. @Alemito managed to find the correct wiring images and we managed to get it working fairly quickly.

Case closed, onto the three diff bushes this afternoon!

Excellent! Tbf, most observations were tending to suggest it was incorrect connections, but your headache has saved the rest of us from the same thing, so thank you very much for continuing the thread to it's conclusion.

Always keen to put resolutions in on forum posts and I hope it will help someone in the future!

If anyone is wanting to install cruise control, all in it was £300 direct from BMW for the stalk and loom, and if installed correctly, takes about an hour. You’ll need a Philips screwdriver and a crimp tool and that’s about it.
