I posted this is another forum and was pointed here.... I have a 2002 Civic SI. I had an aftermarket stereo system installed, with the amp mounted on the back of the back seat. I wanted to check and make sure that they gave me enough wire so that i could put the seat down, and when I did there was a big spark, and ever since my security system will not set. I can lock and unlock the doors with the remote, but the lights don't flash and it doesn't beep like it first did. I'm assuming it is a fuse that needs replaced??? If so, what fuse because the manual does not show which number fuse the security system is on nor does the labeling on the actual fuseboxes. Thanks for helping ahead of time!
