Hi VolvoJoe,

I have the 92 wiring diagram manual in my lap. I have some of the relevant pages from the 91 manual scanned. When I compare them, for the pages on cruise and the hi/lo selector, they are the same. The switch that pulls in the hi/lo relay on the left fender uses a brown wire. The only thing I see using a blue/red and white/black wire together is part of the cruise control, but not part of the cruise switch wiring. Those wires run to the clutch pedal and brake pedal switches. I hope you're not trying to find where the clutch pedal switch wiring runs on an automatic, for that may have been unconnected when you started your project. In any event, look at the brown wire to fix your hi/lo switch.
