6610 starter switch diagram?

[Gwiz]

Can anyone email me a diagram or picture of the spades on the back of the starter switch for a 6610 manufactured 12/85 with deluxe cab. Or a good description and wire color code.
Can't seem to find the correct spade for connecting the thermostart. Suspect the switch must be bad.
Thanks
James

According to the shop manual, there is a Brown and Red wire that goes to the start position connector on the key switch. It's the last position on the keyswitch and it runs into the #1 POSITION ON THE NO.1 BULKHEAD PLUG. It actually makes a connection to the Thermostart BEFORE the starter acutate position and stays on during starter running.
