I'm a Mustang guy (don't hate!) and I'm building an '89 Must with a turbocharged 4 cyl. My cooling system consists of an NPR I/C, Volvo closed system radiator and a '91 SC cooling fan. I'm about to wire up the fan. My question is what amperage relay do I need??
I've heard talk of relays needed as high as 90a due to the inrush current. However, I noticed this diagram that says a 30a relay is sufficient...............

The above diagram has 2 wires from the fan. Mine is a high and low speed fan motor with 3 wires. Does the high speed require more amperage? Can you guys clarify this for me?
BTW, for anyone in Northern California needing parts there are no less than 4 SC's in the Windsor Pick-n-Pull yard right now.
