Help in wiring K-line 0-42 Switch

[taylorl]

I recently picked up some 0-42 K-line remote control switches at a yard sale. They have no instructions and the remote switch machines were cut off with only about six inches of wire to them. On the switch itself, it has 5 connections. The first two terminals has the word track written under it with a letter F under the first connection. The last connection has the letter G on it. Need some help in connecting the remote switch machine to the switch. Could someone give me the proper wiring instructions? I have a lionel CW-80 transformer. Thanks
