Message: [QUOTE="gnxtc2, post: 1223514, member: 1414"] So I did the conversion using the Horton fan clutch. Wired in a manual over ride switch, coolant 210° NO temp sensor (192° T-stat) and AC high pressure switch/pigtail from a Taurus (don't have the part numbers off-hand). The AC switch has two sets of contacts, NO/NC. The factory wiring goes to the NC contacts and fan relay control goes the NO contacts. When the AC pressure goes up, it opens and the fan kicks on. All the sensors/switches are wired independently. Everything works as it suppose to. I am controlling the negative side of the relay coil. What I'm experiencing with AC and its now warm enough for AC use. If I'm cruising on the highway at 70....water temp is down but the AC pressure built up which activated the fan for 5 secs. I am thinking about installing a manual shut off switch so I can kill the fan on the highway and leave the coolant temp sensor to over ride the switch. On a side note: My AC compressor never seems to cycle when the AC is switched on, it always says engaged unless I turn the switch off. I sucked down the refrigerant and changed out the orifice tube (red). There was a few piece of metal on the tube (AC compressor going out). The low side was around 40 and the high side was around 300. On long trips, the evaporator would ice up and have to switch to vent to melt the ice. This issue was present prior to doing the Horton.
