It doesn't matter if it's a suck or blow fan... an 8mm nut driver and a quick flip of the fan blades and it's gone from blow to suck.

Not necessarily - Davies Craig fans, for example, require you to flip the blades over and reverse the polarity. Sounds a little counterintuitive, I know, but it does work. RTM applies in these cases.
And yes, relays and fuses are a very good idea I would be surprised if there wasn't one of each included in the 'wiring harness'.
Considering the problems you've been having, I wouldn't recommend just drawing the power from the 'old' source, although it may well do as your signal for the relay. It is rare for the ECU to drive a fan directly, but rather it provides a signal to a relay. Trying to use that signal to power a fan could well lead to fried bits 
The power feed itself needs to be fairly heavy wire, and can even come direct from the battery if it is going to be switched and fused.
Good luck 
Edit: Spelling!
