hi, new here..

I just ordered this hvac control unit for my 02 buick century.. What tools are needed/ what are the instructions for installing the HVAC? It looks like I'll need some sort of wiring connectors? thnx

 

fixed it.... just had to remove the side panel on the dash by the door, the dash part under the steering column, and the dash piece around the hvac. Unplugged the old one, plugged in the new one one and put it all back together. Used the sticky thread about removing the dash as reference.
