Ok, picked up a nice large electric fan from the pic n pull this weekend. I am trying to wire it up but have a couple of questions (its a ford fan large sedan fan) 1) it has three wires Black- I'm sure its ground Blue - ? Orange/grey - ? 2) I tried wiring without the blue thinking its the AC connection to kick in second speed, but I am getting no fan. 3) Also, I bought a fan controller with thermostat and connected the red wire from that to the battery. I also need to connect the yellow wire to an ignition+ source. Any ideas what best connection would be in engine compartment for that one? (350, carb'd, no A/C) thanks, I'm frustrated.
