[Fot] Adding type A OD

[fmccjr at aol.com]

Mine is on the gear lever (toggle switch), but I wired an led on the dash to tell me it's engaged. Now I don't forget!

To combat this I used a standard electrical control scheme called "Three wire control" to engage the OD relay but drop it out when the shifter switch opened.  To re-engage overdrive a pushbutton would activate the relay and latch itself in so the pushbutton was just momentary.  Does that make sense?  I can do a drawing if not clear.   Steve
