Where can one get a detailed schematic wiring diagram for a kaz psk7799-og electric heating pad and control?

The real model # for your heating pad is ...HP980

I just managed to claim mine as I had no heat anymore . The circuit was to difficult to trace. You can call 800-477-0457 or email consumerRelations@kaz.com

It worked out OK for me . They gave me a RMA # and I sent out the old one and am now waiting for the replacement.

Good Luck
