sr240Mike those fans are IDENTICAL to what I have on my 240 right now. Since the above posts I made, I have had no cooling problems at all, and the car doesn't sound like a UPS truck during accel.
I have since replaced my radiator, so after I reinstalled my fans I just used zip ties on all four corners. Above I mentioned that the fans have to be very close for good cooling, but I think that might have been due to the fact that I was a little low on coolant at the time. Since these fans don't have the best shroud I think it's still important to get them as close as you can to the radiator for max cooling.
Also, watch out for the AC line (iirc) on the passenger side, as it will sometimes interfere with the passenger side fan. If it's touching the blades (you'll hear it) then your fans aren't close enough to the radiator (or they have slid back!).
When you do the wiring, each fan will have 4 wires. I think they are similar to dual-voice-coil subwoofers, having 2 power pairs (+ and -) for each motor. At first I thought they might somehow control fan speed, but after I played with them a bit I found that was not the case. Just wire up one pair for each motor and you'll be fine.
Here is the lamest wiring schematic you've ever seen:
M = Fan Motor (left/right)
chassis ground <-----[LM]+++++\___ blue ACC relay lead (on with key)
chassis ground <-----[RM]+++++/
Good luck to anyone doing this project, my advice is to do your homework and find something that fits, because you aren't going to enjoy this install.
