Certainly on the mk1 there are the correct pressures shown for the tyres (each size listed separately) inside the fuel filler cap, these should agree with the handbook anyway. I just run at those, though if you run at the fully loaded pressures when the car isn't fully loaded the handling/ride quality can be somewhat worse than it should be. Though obviously as size/weight increases the pressure does have to increase, and the Galaxy is around 1.8 tonnes upwards anyway depending on spec.

Been thinking about this - the other way you might be able to approach it is to splice the existing kit into the door lock motors on the existing door lock instead (using the kit to control the existing locks rather than the ones its supplied with). Would take some working out to see what way is best to tackle it, but probabbly end up more reliable than trying to attach to the door handle cables (as they also allow you to open the door I can see this might be more problematic than it first appears).

They pop up on ebay at fairly cheap prices.......
