Hi, The wiring diagram is no problem but you didn't say what type unit or model number? Are we talking heat pump, split system, package system, strip heat and etc. Goodman is as good a unit as anybodys in my humble opinion. They are also very bargain priced with easy service features and readily available replacement components at just about any A.C./ Heating / and Appliance Parts Store. Goodman has a web. site as well so I suggest you go to it and find out whom your local dealer/distributor is so you can get wiring diagram if you've lost yours that came with unit. Goodman is also very good about putting a wiring diagram somewhere on the inside access panels of all their units so be sure and look there first.
Probably on the inside of one of the cabinet covers on the unit or Goodman .com
