I need to hook up a 3 speed switch (HAS 5 Terminals) for a heater/AC FAN. 1 wire goes to fuse box, 1 goes to the fan motor, What happens to the other 3 ??
NOT in a Fiero, * It's going into 1 of my "Older cars" with No Original 3 Speed Fan. * Please help. Thanks

They run to the resistors to control the fan speed.



and it is going to wire something like this

That's a little more Complicated than I wanted to get, remember this is Not in a fiero. I found a switch WITH the resisters "on the switch" and only 2 wires, 1 in 1 out. Hopefully that will work.
