All the info I've found is for 93 and newer probes. Does anyone know if it's the same procedure for a 92GL??

Just ground the STI connector, it's a single black 1pin connector. Ground it to the strut tower if you'd like. Then get in the car turn the key on accessory and record the CEL light flashes
