I have a 64 impala ss with 3 speed o/d . Is the overdrive handle in or out for overdrive? I have the fused wire connected to the hot side of the relay. I am getting 12 volts to the o/d relay. I am getting nothing from the o/d relay. When and how do I get 12 volts out? Should I get 12 volts out with the key on ? Any ideas on getting this o/d to work would be appreciated.

Trace the wiring out in the old car manual project. The lockout handle must be pushed in, the governor must be up to speed (approximately 35mph) take your foot off the gas and it should engage into overdrive. You should hear and feel it click into overdrive. You mention the relay, do you have the rest of the components? Solenoid, kick down switch? It would be best to have it all connected as originally designed but to check it you can bypass certain components with a toggle switch directly to the solenoid. The problem is that if you are not careful you can damage some rather hard to find parts including the wiring in your car.

I now have everything hooked up. I have driven the car and everything works except the kickdown switch. It may need adjusted. Thanks to all.

Be careful with the mounting of the kickdown switch. I once had a '68 Impala wagon with a 3 speed overdrive transmission. On the way to work one day to avoid waiting at a stop sign too long I goosed it pretty good. It had a 275 hp 327. The linkage went past the kickdown switch and jammed wide open. Things kinda went downhill from there.
