Hey guys i picked this car up a year or so ago and it was switched to a carb at the time..im doing a complete resto with it and finally narrowing down all the wires and crap that was done to it. But i need to verify this green single wire as it can only be the secondary fan switch wire i hope, also the switch is supposed to be located between #3 and #6 right? Well its plugged. Oh and the wire is with the A/C wire loom.

Without rummaging through some diagrams, iirc, the secondary fan wire to the fan switch would be grey.

The fan switch is located between the rear two passenger side exhaust cylinders 6 & 8 (cyl 3 is on the opposite side of the block)

The harness plug for the (OEM) fan switch is the same as the knock sensor (located just forward of the starter)

I cant find a grey wire? and it currently does not have a switch either and i need to get this resolved somehow?
thank you "Deadbird"
