I have two tractors that each died a different death. The M5666 engine ran away and blew, the M5040 lost a transmission. So I decided to combine them and since the newer one was shuttle shift I machined the flywheel from the M5040 to match. Got them bolted together yesterday and it runs and drives, however the wiring is from the M5040 and I can't get the dash to work. Acts like a ground missing but not sure. Anyone have a wiring schematic for this M5040?

Well the issue was a ground missing. Have a few odds and ends to button up and put it back to work!
