All done thank you for all the input and guidance i had a couple of those vacuum switchover valves from a 93 300E i raided a while back at the junk yard. So my Astra 4000RS Remote Start/Alarm/Key less entry is all in with all it bells and whistles on my 1991 300 D 2.5 Turbo.WVO The best part about it is that my home automation software and computers can turn the car on for me every morning at 8:40am so at 9 is all good to go and i dont run the risk of breaking seals and plastic in the transmission for being late and driving the car cold as soon as you turn it on.
thank you all
Denis
