Heater levers - Are they the same way round on a LHD as RHD? My cables and levers have no coloured knobs on them so I don't know for sure, plus they are all so stiff they need a good clean/replace...
What I meant was the cold is attached to levers not cables, so blue on that (or them) and red on t'others.
On a right hand drive, if it is like mine there are 4 arms under the dash. The left hand one is blue, next one is spare then the two reds
have a look in the Major the Westy (Show us your Ride section) - there are photos of the heater levers and the layout of them on the dash!
