I am needing wiring schematics and Heating & Air Conditioning schematics for a 1977 kingsbrook manufactured home. Serial numbers A1488 and b1488.
Could you please email it to me at ***Email Removed***

Thank you
J. Jones

That's a bit of a reach here. Suggest you try a mobile home parts place, Google didn't help.

There are also some mobile home forums such as mobilehomerepair.com that have HVAC forums.

Good luck.
