Ignition Switch Wiring
Trying to get my 51 F1 running. The key wouldn't turn in my ignition switch so I got another switch off ebay. Long story short I broke a post on the new switch. However, I managed to get my old ignition switch free with some oil. Problem is I don't remember where the wires went on the original switch. There were 4 wires total. One post had 2. The push button start is stuck as well but it also wasn't hooked up. I've tried searching the forums but can't find the answers i'm looking for. I'm lousy at this electrical stuff. Am i going to need another push button starter too? Any help would be appreciated.
P.S. You have to respond like you are talking to a dullard

There are a couple of significant errors in Julie's diagrams in the linked thread. I would NOT use them.
It sounds like your ignition switch is one with a starter function built in (not original). I would guess the four wires are:
Battery power (largest, maybe red)
Power out to ignition and gauges
Power out to Accessories (maybe going to a fuse panel?)
Power to starter solenoid
It isn't unusual to have multiple wires for accessories or other loads coming right off the switch posts. All you can do is trace them out and put labels on them. Once you know where they go, you can figure out which post they go to.

AM = Ammeter, the battery wire is connected there
Coil is pretty obvious, ignition, so one of the two wires heading towards the gauges must be ignition. You need to trace them further.
GA/RAD is the accessory terminal, so everything like gauges, radio, heater fan blower, etc should go to that.
