Randomly my domelight will flash on, my horn will honk, and I think the trunk light will flash or at least some sound from the trunk all at the same time? It just started happening about a 1-2 weeks ago. I allready reset my alarm so Im pretty sure its something in the cars factory wiring (cars a 1995 ford mustang gt) and I MUST find and fix it myself since Im not rich and dont have a few thousand to spend on a tech. to trouble shoot and fix it. Any ideas on what it could possibly be or how I can trouble shoot and find it myself? Im pretty good with wires as Iv rewired a few older cars for people before but never dealt with anything fuel injected so I dont even know where to start. Computer, fuse box...
