Holy crap why would you spend $90 bucks on that. Dude go to schucks and pick up 30feet of wire for $2.69 then a relay for erm..i forget, cheap! then a $2.00 switch and $1.00 in connectors. Pull the harness from your fans and hook the wire with connectors to it, they'll clip to standard "blue" connectors you can get at the store. Route those to the relay and into the cab to the switch you have ready to be mounted. Mount all that and hook to the battery. Boom, now you have control over the fans and you paid a couple bucks. I did this on mine so if you want a more detailed how-to I'll try and put one together.
Stuff got done.
