Need help rewiring ingnition switch on a 1520

[double hunter]

Just bought a new to me Ford 1520, someone has replaced the igntion sw with a 4 post switch and installed a push button on the dash,,the glow plugs are not working making it difficult to start, if someone can tell me how to rewire this thing I would greatly appreciate it, I have five wires, (1) a large red, (2) a large red with a white tracer, (3) small solid black) (4) 2 large blacks with a white tracer,these 2 are not connected to anything,, any help will be greatly appreciated, it sure looks like it would have been easier to replae with the correct switch instead on re-engineering.
