Well I finally got the engine in, it started right up, ran flawlessly for the 30 mile test drive, everything worked, when I went to leave for home the aftermarket alarm system disabled the friggin ignition. I removed the entire alarm system and still no luck. Everything else works... lights, stereo (comes on but turns off again) but I have no ignition/dash lights and no power windows,locks, etc.. I checked every fuse, have new cables, good connections, blap,blap.
Any clues as to what might be causing the problem? I can turn a wrench like there's no tomorrow but electrical isn't my bag.
