Relay attached to rear of speed/tach

I'm just finishing up with some wire restoration on a '67 RS/SS fact 4 gear with pwr windows. (it's incredible what can be done to a 42 year old car and its wire). I've got the windows working fine, however there is a relay that is attached to the back of the speedometer/tach housing that has me stumped. The harness/plug that connects to this relay has a WHITE WIRE that plugs into the relay and also gets connected to a post on top of the housing (I'm thinking ground), plus the harness/plug has an ORANGE WIRE that gets plugged into the relay, if you trace this ORANGE WIRE back it wyes to two plug connections which are not plugged into anything, and I don't see any 'empty' plugs. Finally, (IMO) there should be a third wire but sadly there is not. I'm thinking there should be GRD, IGNITION for the relay coil, and a larger gauge wire for LOAD, what ever the load is.
I've searched the threads for several hours but can't find the info I need, and I've poured over the wire diagrams but can't get the answer.
Thanks for your help, Ron

Re: Relay attached to rear of speed/tach

John you nailed it. Thats what it is, I did a search for 'speed warning' and there it was, a picture of what I assumed was a relay.
Thanks to Ed (Bertfam) he had a picture on a previous post. Plus other posts confirm that the plug only has two wires, now to figure out how this gets wired, uhmmmm.........

Thanks again, Ron
