ok so here's the scenario. Got a 90 Fox. Just finished the 3g 130 Amp alternator, install.

Now I picked up a Taurus electric fan complete with the pigtail. I know there is a retarded amount of threads out there for a Taurus install on a fox, but it seems there are some major differences.

Install options that I have found:

1. DCC controller

2. Flexalite's VSC
Flex-a-lite 33054 - Flex-a-lite Variable Speed Controllers - Overview - SummitRacing.com
3. Hayden
Hayden 3647 - Thermostatic Fan Control | O'Reilly Auto Parts

I just purchased the Hayden controller. Which has a 30amp capability. But after doing some more digging, finding out that the Hayden controller doesn't have a soft start capability. Which from what I have read is required for the taurus fan due to it's initial startup amperage. From what I have found some people use this controller with the 30 amp relay that is part of the controller. Other installs I've seen people just get a dcc. And other's use the summit racing vsc and a 75 AMP RELAY.

Being that I have the 3g 130 amp alternator I know that's covered. Can I use the hayden controller with a 75 amp relay? Or do I need to take it back and get the summit racing model with the soft start capability, and a 75 amp relay?

(DCC is out of the picture right now. I can't wait 2 weeks for a controller)

 

soft start would be best but the 75 amp relay set up should work fine, prob with hitting the current all on at once there is an initial current spike until the fan gets up to speed......the soft start slowly ramps the current up and is better for longevity , but both should work fine
