Hi need some help in locating a wiring diagram for my car, its a 1993 wrx import.
Having some major issues with ignition barrel and it cutting the cars power.
After some closer inspection under the dash ive found that the wiring has had a massively bodged repair which means when i turn the key in the ignition barrel it completely cuts all the electric in the car this includes lights inside and out, radio turbo timer and boost guage. any help please would be appriciated.

also i found a single plug under the dash not connected plugged it in and the check engine light kept flashing whats that about ???
