Guys, just did this conversion on my wifes 2006 Gen 1 ZX went pretty well total crap instructions though.
Pulled both side fairings, removed ALL radiator attachment bolts (3 of them) this allowed much more access and movement to get the fan in place.
Installed as high as possible and as far to the right side of the radiator as possible, pushing the attachment zip ties through the radiator was a bit spooky, LOL but it went very easily and I only got 3 of the 4 on there as it would have been a bear to get my big hands over to the last one and I am pretty persistent.
I installed the fan with the wiring pointed in the direction ofn the factory fan and used a power tap over by the factory fan plug in to get 12v+ and then found a nearby bolt to attach my 12v- ground to, carefully inspect and attach yur wires so they wont get hit with the factory fan as it really has no housing.
Double and triple check all of your bolts and wiring an test everything before you put bit all back together I tested my fan switch with no ecu and it worked perfectly.
I also added a secondary fan switch which I got from smartmoto.com (no affiliation) this plugs right into the factory harness with NO cutting or splicing it still allows all of the factory fan on/off times yet with the flip of the switch BOTH fans start blasting the heat away, it is an awesome kit for less than $40 bucks shipped from Greece in just a few days.
MY last cooling improvement is that I sent my ECU to Nels at 2wheeldynoworks to give me the flash and also have the fans come on at a lower temperature.
I have not got it back yet as I just sent it yesterday but he flashed my 2nd Gen and it is AWESOME with 206hp at the wheel.
Hope this is helpful to someone to prevent the sensation of an overheating 1st gen ZX.
Cheers.
