Ignition Switch help

[birddog019]

Well I got a new ignition switch because my '71 40 didn't have one when I got it. I'm trying to figure out which wire goes where. There are four conectors on the switch and I need to know what color lead goes on each. I've tried to figure it out with the diagram in the haynes manual but you all know how that goes. Any help would be great.

Thanks

The wireing diagram I pulled from the Tech info here is for a 71. It says :
BW to starter, BR to AM (hot from Amp meter), BY to ignition. My 71 has a generic swith from NAPA wired in but I think the OEM one has a plug at the end that pluges into the harness.

Thanks, but the connectors are not labeled and I don't know which one is the starter, amp, and ignition. If there was a plug, it has been cut off. Any one with the same style ignition switch (in dash) know if there is a plug to the ignition switch? If not could someone let me know which connector is which?

OK use a meter.

Off - nothing is made.

On - amp and ign will be made.

Key held on starte - amp and starte & amp and ign will be made.

may have a 4th post for accessory postition but don't think you use it.
