79 Power Wagon wiring questions...

Need help figuring out which light in the dash is for the " Transfer Case Loc" , "Fasten Seat Belts", and "Check EGR".. Does anybody know which color wires goes to which lamp?? Thanks for the help...

I had a 79 4x4 warlock and a 79 ramcharger 4x4 and never seen any light but the "loc" light up. And IIRC, that was a bulb on the end of the two wire harness.
