Where can I finad an on-line wiring diagram for a Payne Gas Furnace Model 373LAV024035

Payne's sister company "Bryant" actually makes that particular model.
(Company was formerly "Carrier, Bryant and Payne")
The wiring specs are found in the "Installation, Start Up, and Operations" manual.
It can be mailed or e-mailed to you. Call 1-800-428-4326 and choose the "Bryant" prompt.
Best wishes~
