I fitted one a few years back. It worked off the alarm fob, as there was an aux button on it that I used to trigger a signal to the relay for the solenoid. I don't remember the solenoid model or make and I have sold the car now. It was just a generic door opening solenoid and was probably a bit beefier than needed - it made a pretty loud clunk when it operated!A while back somebody wrote that they have a solenoid in the trunk to open it and that they would check and tell me what model it is so i could buy one but seems to have forgotten it, reminder?
Yea it take patients to work on an Alfa Romeo spider. I do not have a lift so working under the car is a real pain.
