just remeber one wire is slow speed and one wire is high speed, I will look at my diagrams and let you know which is which.

That is technically correct, but unless you control it with a 94-95 ECM, either wire is high speed only.

The fan runs two speeds by ECM control. ECM grounds the fan at something like 6v or so for low speed, and when it wants high speed, it grounds another ground and supplies the fan with the full 12v...

So, either terminal will give you full power if using a switched souce...

Interesting. Neither one of my fans would do that. Brian or I had to hook power to both of the fans I have used in the past to determine which was high speed and which was low.

I wished I would have never wasted the money on the electric fans now that I am back to manual.

You were running taurus fans, right? I know for a fact the dual speed was like that on the mk8, and was pretty sure on the 94-95's, not sure on the taurus...

That's weird. So, why would you need two wires then?

Lee is correct on the Tarus fans. We have had 3 different fans and all had a noticable difference between 12V on the "high-speed" wire and 12V on the "low-speed" wire.

Perhaps the mk8 is the only one that did it that way, I dunno. I know that I tried either + connection on it and the fan was the same speed.

I assume that one wire was 6v, and the other wire was 12v. Or possibly each wire was 6v, making a total of 12v (disclaimer - I don't know jack about dc voltage/electronics, 100% home taught

)
