Goodman GPH1336H21AA heat strip connection

I purchased a Goodman GPH1336H21AA packaged heat pump, at the same time, I also received an HKR15CB heat strip with 60 amp and 30 amp breakers. I had the work done my a local electrician. When he went to connect the heat strip to the heat pump he noticed that the female plug on the heat pump has 3 rows of 3 circular openings to receive the male connector from the heat strip. The plug has black, white, blue, brown an purple wires. The male plug from the heat strip seems to have 3 of the connectors squared off, acting as a key and the plugs will not connect. He said he could remove the plugs and connect color to color, but noticed that the male connector had a red wire that the female plug did not. He also noticed the both the black and red wires to the heat strip plug connected directly to the 60 amp breaker indicating high voltage and noted these 2 wires were not as thick as other wires that carry the same current. He said he would have expected the 2 plugs to only contain low voltage, for control of the heat strips and not any high voltage. He is not an HVAC expert and not wanting to cause any damage to the unit, he did not connect the heat strips. Any help you can provide would be appreciated.

Contact Goodman or whoever sold it to you and set if they sent you the correct strip kit. Sometimes there is a TSB service bulletin or retrofit.
