3020 ingition switch help!

Both my father and brother are away for the weekend and the parts people are closed so I'm hoping someone can help me. We have a 3020 push button start tractor and the ingition switch needs changing, sounds easy and it was until I went to change the wires, the switch I took off has the wire prongs? in different places then the new switch I have. on the old one there is one on top two on each side and then another one on the bottom. but nothing is labled to tell me which wire is which but on the new switch it's more scattered, but those are all labled so what I'm hoping for is that someone knows which wire is which on the other switch so I can match them up and put them in the proper place on the new switch, because I'm thinking if I put one of the wires in the wrong place I'm going to blow the electrical and well we don't want that. :)

Thankyou to anybody who can help.

Just put the bulb between 2 terminals, record the results (on or off) and push the button...then record those results. Won't take but a minute and you aren't going to hurt anything. Then just match the functions and you are there.

I'm going to guess that battery voltage goes to an input terminal. Then since I recollect you said or eluded to 3 terminals, a second terminal will be connected to that input terminal regardless of the button and the start button (when pushed) will put the voltage to the 3rd terminal which would go to the starter solenoid. The second terminal would just be a voltage supply terminal (convenient place to get voltage) that might go to the lights (light switch)or something like that.
