I just picked up a 312-8. The previous owner was irritated with the warning lights on the dash and wasn't happy with the design of the open terminal strip and small gauge wires so he removed basically everything wiring wise except the heavy gauge battery cables. Then realized he couldn't remember where anything went. I guess at this point, I could find the wiring diagram and start from scratch or hope someone has a harness. I will try to post the model number since I can't seem to figure the Toro site out with the model #'s.

hi handyman. wish i could help, but all my horses are older. simpler wiring with no bells or whistles someone here will be able to help though. hang in there. jim.

i have wiring diagram for a 1989 312

Smitty, That would help. I know this one has the warning lights in the dash which I am not going to rewire. Just the basics to get it running and have the lights and safety switches work. Thanks.
