Thanks El, that relay combo looks like just the ticket. Before I start investing in the controls I need to see if I can make this sucker fit. I took some preliminary measurements before I bought the fan. It may or may not fit behind my radiator. It will, at best, take some creative carving on the shroud to get it in there. My core is only 18" wide and the distance from the radiator to the water pump pulley is only 4" as the crow flies.

Was I right on the SHO fan? Where did you get the info that that fan you posted was from a SHO?
