Only Cub Cadets - 1861 cub cadet wiring diagram

I am new here so maybe this is the wrong place to start and I have looked on here and cannot find what I need. I'm 75 years old and not on the computer a lot and don't know my way around the web. I am a full time caregiver for my wife so don't have the spare time. That being said I am in need of a wiring diagram for a 1992 1861 Cub cadet serial # 000826089. I bought it new in 1992 or 1993. I found diagrams but they don't match my tractor. I am working on the PTO wiring, relay and PTO switch. My PTO switch # 925-0893 is 5 prong with no numbers or letters or markings. The relay is # 925-1975 with 5 pins, They are marked as 30 85 86 87 and 87A. The PTO only runs if I hold switch on start position. Replaced Ign switch, PTO switch and relay. I am good at wiring and mechanics and reading schematics. So if I can just find the wiring diagram i will be able to figure it out. I can get it to run by bypassing a lot of switches and relays but don't like running it like that. Thanks to everyone.
