I ordered a specific part using the correct part number for what I needed, and they send a sub version that had different connectors (same housing) but different outputs. They could not understand my need for the correct one. After no phone support, and emailing for over 1/2 a day I told them to give me an RMA so I could return the part.
I called a different retailer (SupplyHouse.com) and got the correct part next day air'd within 5 minutes.
I wouldn't recommend doing business with NorthAmericaHVAC
