Need Location of Anti theft Computer, Fuse Blows
 

HI I own a 1985 Toyota Supra, for years my anti-theft always goes off when I open the door even with the key. The other day I noticed my Dig. clock, Dome lights, Key Buzzer, & anti-theft no longer work. I found the 7.5 amp Dome fuse blown. When I put in a new fuse it blew again so I know I have a direct short to ground. So I think either the clock or anti-theft computer is bad. Also can I disconnect it & still get the dome lights to work ? or can I disconnect the dig. clock if its the problem ?

I really need to know the "EXACT Location" of the Anti-Theft computer in my 1985 Supra. THANKS RAT
