Got the exhaust on today, then worked on the wiring for the eFan and the PTC
Using the Volvo 2 speed fan & relay - wired using the old AC fan relay signals (components 82 & 495, BL-SB wires). I separated the Rad thermoswitch (224) from the AC circuit, using the AC circuit for speed 1, and the thermoswitch for speed 2
of course the AC circuit connectors all fell apart when I separated them for circuit testing, so I'll have to deal with that
Repurposed the BL-GN relay feed (switched power from Fuse 9) for power to the PTC (Note: bad idea, PTC shorted & killed the AC circuit)
Putting the relay and fuses on the coolant tank - but.... had to acid dip the bracket to restore it first
made a new mount bracket that attaches to the existing, to retain 2 relays and the fuse/holders (9494667), final pics later on.
Ran the engine until warm, and fan cycled a few times. Amazing how quickly the engine warms up now it doesn't have the fan clutch running....
