Does anyone on the list have experience adding the factory AC wiring
to a non-AC van. The only part I'm interested in is the 3rd speed
radiator condenser fan and which wire triggers it.

I'm going to be using a different condenser and evaporator and just
need to wire in the needed relays or wiring to activate the fan and
wire it into my system so it comes on with the compressor. I've got
all the wiring and relays from a parts van that had AC but I'm having
trouble figuring out what I need and don't need. My van is a 1987
syncro transporter so I've already got the fan used for the AC vans.
Looking at the manual I think all I need is to add the 2nd and 3rd
stage fan relays. One looks to be above the fuse panel and other is
behind the left fresh air vent but I'm not sure about the trigger
wire that activated the 3rd speed.

If any knows please pmail me,

thanks
