'00 - '03 Ford Focus Fan Wiring

I need some help.

Can someone give me details about the cooling fan set used in the '00 - '03 Ford Focus? Pic below for reference.

I would like general information. Amperage draw per fan, and CFM rating per fan. Are they one speed, two speed, variable speed? What's the factory control like?

The other question I have stems from the wiring I see in the picture. It seems the wiring from both fans meets at a junction of some kind. Is this just a junction for the two sets of power wires or is this a built in controller or relay of some kind?

I will be using this fan in a custom application on a '77 Vette, and am needing to know how the fans are controlled so I can possible incorporate that into my plans and how I had originally designed my system for a different dual fan.

Thanks for the help.

According to a Mustang owner who installed a Focus fan, that junction I see is a resistor of some kind for the high power fan. I guess it's prone to failure?

Yeah, I believe that's the thermister pack. They have a tendency to go out. However, I must confess that I've only seen a handful of actual cases of that occuring in my browsing of several Focus boards.

The resistor is used to get low speed. Be sure to use large enough wire and relay able to handle current draw. Not sure of the exact draw but they do use a 50 amp fuse so it could be 25 to 30 amps. Connector failures at the resistor are common mostly due to close proximity to the exhaust manifold.

Curious, is that a 50 amp relay for both fans, or per? The way I have it set up each fan has it's own separate control and will have a 30 amp relay. I will upgrade those to 40 amp relays, and it's all fused through a custom fuse box I installed under the hood for 12V constant and IGN sources for accessories.

Fuse is one 50 amp for both fans so 30 amp relay one for each fan will be fine.
