For my Suby 6 conversion I've installed a twin fan system (from a Dodge) on my radiator. One is single speed (3 wire) and the other is 2 speed (4 wire). Which one of these 2 fans comes on first? Do they both run at times? Will I use the 2nd speed of the 2 speed motor?

Thought I'd add this bit of info re: this style system. Last week I noticed that my fans were working on low but when switched to high (yeah, I was chasing a cooling issue) it dropped to Fan #2, only. Following the chart I was able to determine that relay F, in my case, (relay 3 in the diagram) was at fault. I was quite proud of my diagnostic abilities and proceeded to remove said relay to bench test and verify what I knew to be the problem. But the relay tested good. (IMG:style_emoticons/default/WTF.gif) If it had been a snake it would have bitten me. And it's not like I didn't know it was there; I built the damned thing. I just forgot they were there. The fuses are now labeled for my benefit in case I blow another one. So if this one blows I get the above described scenario, however if the other one blew I think none of the fans would operate but you might want to double check me on that one.
