You can get the wiring diagrams for earlier model MKIII's there from the 1987 repair manual.
The AM2 circuit goes to the efi and ign fuses. Ign fuse is through the ignition switch.
When does the fuse blow?

You have to get a multimeter and use the wiring diagrams to trace the short.
Does it happen without trying to start the car?

ok got it figured out i had some crossed wiring to the b1 connector in the dash so everything was being routed to the am2 circuit. fixed the wiring and the issue went away
thank you all for your help
