Just finished an AC conversion on our 8050. New Sanden compressor, all new hoses, filter/dryer, expansion valve block and New Evaporator / heater core. The system works great. The new compressor clutch has a single wire and grounds through the mounting bracket. Curious if there is a way to utilize the original Low Pressure switch so the Yellow Low Pressure Dash light still works?

Short answer is yes. Don't remember the details but involved reading wiring diagram and duplicating it. Right wires connected to right wires. Did my 8070 2 years ago. You will have to figure it out but know it's possible.
