The Ford diagrams are terrible. Get one of the ones available from Langs. Also, good ones are posted on the forum occasionally.

Since you have a '21, try this one. You can blow up the view on the screen by holding down the CTRL key and scrolling with the thumbwheel on your mouse. :-)

thank you Garnet--Larry--Mark,the diagram posted IS a bit different,in that on the terminal block it shows the red wire in a different place than the others do,also, the terminals on the back of the key switch seem to be different than the one on my t, I will remove the switch assy this after noon and compare.but so far I still have no idea what wire feeds the battery side of the key switch.for starting the engine, then switch to mag for running.I will give Steve a jingle and get there diagram. that's where the wires came from. thanks again.GREG

It has been my experience that there is no ground wire on any switch that I have worked on !!!!
Don't be surprised if there is none. JMHO

Richard,

It's the yellow wire through the ammeter.

I may be closer to not solving my wireing problem,rob wolf posted a wireing situation in 2008 on tuesday, grrrrrrrrr, that switch is the same as in my ford.the wires are not at all like the the one in the diagram that Mark posted for me. I'm going to call Steve at Langs and get there diagram. thank you all for your good help.Greg.

The wiring diagrams at Texas T Parts are really good.

I used theirs to completely rewire my 24 Touring. It's flawless now.
