chargedstang89,
You can buy a heat activated thermostat from
www.jegs.com or
www.summitracing.com They sell parts from
www.painlesswiring.com I'm going to one the switch from Painless. The fan is activate by heat. They have two settings to chose from 200 on 185 off or ~190 on and 180 off.
For the hose wiring check under the hood. There should be a small diagrm there. If not most parts stores have a Chilton manual available with the diagrams.
