hey guys
in the process of re-wiring my 85 and all diagrams dont show were pto warning light is wired into. previous owner had it going into key switch and wire was off out on pressure switch. if someone with an 85 could tell me were leads from light and switch go i would appreciate it.
 
Gas or Diesel? Line pressure switch is lite ground if I remember right and on below about 120 PSI. Switch opens the circuit above 120 so lite goes off. Diesels turned lite on with electric fuel pump switch while gas used the key switch to power the lite. Lite should also come one when foot clutch is fully down to open PTO dump valve.
 
diesel tech thanks, gas 85, so negative runs out to pressure switch and pos to key switch, makes sense to me. thanks again
