2006 trailblazer I6 Efan

[bruhaba]

I've been looking into swapping the viscous engine driven fan on my trailblazer for an electric. I'm going to need the room for the extra belt to drive my m112 blower.

When changing from viscous fan control to discrete, what pins will control the fan on my 06 trailblazer with the 4.2L straight 6?

I've seen mention of the "white wire" that drives the viscous fan, but there have to be at least two outputs to drive the relays for hi/low speed discrete setup right?

Please help! Thanks.

anyone know any detail? Any help out there?
