Thank you both for your replies!
I do not have LED tail lights, the brake switch has a good ground and the cruise control module responds to using the brake lever.
I checked the main ground to make sure the resistance wasn't too high (as per the rostra installation manual).
I'll adjust the engine power settings from your recommendation but my main concern was that the VSS test appeared to be giving me an error code (but it sounds like according to kiltman this is normal behavior).
