TIP: When searching for WIRING for your rig, do NOT search for GS Seahawk, but you WILL find results if you search under the brand/ Model ## for the air conditioner, and/ or furnace and/or Thermostat. This also applies to engine/ chassis, look to Ford, Chevy, MB, etc by Model/ Serial. LUCK TO YA... TIP#2: When gathering Brand/Model/ Serial, use your phone and ALSO TAKE PICTURES, they can save you many return trips to the rig to answer the 1000 other questions
