Just thought of a mod. Any way we can wire in some sort of timer so when we go to work in the morning if its cold heated seats will kick in 10 mins before

I think they might only work off the ignition though? Wonder if such a thing could be done.
A mate of mine had an old beemer 750 which had a complete timer system for the hot air to come on up to 30mins before you got in the car. Nice!
