I picked up a factory A/C setup (from a '79 FJ55) for the FJ55 but my OEM manual does not show anything for A/C on an FJ55. Anyone have the wiring diagram? I also need to know the purpose of the wire from the coil/distributor. Is this to tell the A/C the truck is operating or what? This FJ55 will be 3B diesel powered so there will NOT be a coil or distributor on it! I assume there must also be a relay somewhere in the fan circuit to enable A/C once the fan is running or does the A/C switch turn the fan on? This is the OEM factory A/C setup (Nippondenso) NOT an aftermarket one like Vintage Air.
