Electrical probs. I hate those...

you're going to have to go over everything you did while taking the alarm system out. Your answer probably lies there.

TM is right on. Did you insulate/cap any soldered or tapped circuits that you opened up?

Otherwise, I cant think of anything that would lead to a drain that doesnt blow a fuse.

No chance that something like the glovebox light is staying on (if we have them - I cant remember. My fox does for sure)?

You might have to start tracing it with a meter, and later a test light once you get it narrowed down to one circuit.

Good luck.
