steve why jump the gun, i gpt a clifford on me cossie and the only problem ive had was the location of the proxy sensor
apart from that its been fine
my first thing i would do is find where its al connected as shit instalation ios the reason why these fook up, mine has a proper instalation on it and all done spot on ( unlike the tracker

) and i think thats why ive never had a issue with it
most people with clifford issues get em ripped out and get another alarm fitted in the same location
take it to a proper clifford place who do a decent job ( alot of clifford installers are lazy fuckwitts who shouldnt be allowed to fit a light bulb)
concept 50 is a old system but it was the best at the time and the main problem woth that was the locking ya out ya car by them, the issue you got might me a sensor or the shit wiring
have ya touched any wiring latley before that happened
