Hi, I was looking through the archies about keyless entries. So far I have read about some of you installing aftermarket keyless entries and using actuators for the vacuum lock. I also looked at Benzmac's DIY. However, if I were to buy a german keyless entry kit made for the w124 would I need an actuator? I do not have much knowledge in this. Benzmac's installation seems easy but it does not talk about an actuator. Also his car is a 94.. while I have a 89 260e. Is there any differences? I have included a picture of the german keyless entry kit... Would I need to buy anything else or is everything I need included. To my knowledge this kit is made for the w124 and is not one of the universal kits from crutchfield or other places.
