does it use your orginal heater controls? Did you have to cut the dash?

 

it hooks to the factory controls i had to do a tiny bit to straight out my firewall i believe my car was hit in the front before besides that it bolted straight on.only thing i love about it is it doesnt suck air from the cowl vent so i can weld that shut if i like

 

Was the install easy

 

mine i had to tweak some since i wasnt runing the stock pulley set up besides the firewall fun everything bolted straight on
