I wanted a better quality ignition for my car and bought the sixty dollar-ish Bosch ignition from Sierra Madre Collection. I didn’t realize it is supposed to be paired with an independent starter button. Instead of returning it I plan to pair it with a starter button.
Two questions: 1) Which starter button is other people using? 2) Does anyone have a wiring diagram they can share or would you post the steps for adding the starter button?

Interested to hear how this works out and what you run into doing it. I'm thinking about doing the same.
Robert - Do the instructions say a separate button is needed? I ask because I also switched to a fancy Bosch and was surprised when it would turn past “on” to “start.” I fiddled with it and found that you had to push it in to get to the start position.
If you do end up needing a starter button, I bought one from Sierra Madre, and it is good quality. I can't help you with the wiring. It is fun pushing that button...

Subject to your findings after what Laner said, wiring a starter button is dead simple.
On the back of your ignition switch there is a permanent + 12 v tab among others. Identify it with a 12 v tester over to any ground. You don't want to use that one. Find another that becomes live when you turn the key on to IGN with the tester over to any ground nearby. Keep an eye on THAT tab.
Identify a wire coming up from the starter solenoid to some other tab on the back of the ignition switch. Disconnect that one at the switch. Install the starter button. It will have two tabs on the back. Run a wire from THAT other tab noted above over to either side of the starter button tabs and run the wire that came up from the starter solenoid to the second tab on the back of the starter button. Bob's yer Uncle....twice in this case. Now three times ! Nice fob, Bob.

When I went back to the web description it read that an independent starter button was needed. I’ll double check when I get home from training out of town. I’ll let you know.

That is the button I’m considering.

...and don't forget these!
As long as no one yells, “Fire!!”.
I got a Bosch ignition switch from AutohausAZ.com for about $50. It does indeed have a push-in to turn-to-start feature.
I bought a pushbutton from NAPA for about $6 in the early 2000s and it's still working just fine. I put a 30 amp Bosch relay on the switch, so it should last forever. Terminal 85 to switched ignition. Terminal 86 hooked up to a good under dash ground. Terminal 87 hooked to 12v hot all the time. 87A goes to the starter wire back to the engine. Easy.
Danny:
That looks just like the starter button on the Diamond Reo Semi-Tractor I drove while in college!
Just been transported back to 1970 in Danny's "Way-Back" machine!
I thought the push button was for a different kind of tractor, like a farm kind. I think it meshes well with my other knobs though, and looks the 50s part......
I’m glad I asked the SOC Think Tank. The ignition had a third position. Turn it to the right, push in, and turn it again to start. I’m glad I asked before I drilled an unnecessary hole in my dash. Thank you.
That’s what they pay us for. Hey, wait a minute...
But you could have used that extra hole in the dash to store a roll of Mentos. Or, if your so inclined, you could make it a touch larger to fit a sleeve of Necco wafers!
New England Confectioners Company (makers of NECCO wafers) was sold last Summer after being in business for well over 100 years. The new company (in the midwest, I think) will continue the wafers starting next year. The old NECCO building (850,000 sq. Ft. ) has been cleaned out - It may become a high tech incubator - but the workers say that it still smells like candy in there.

Lane: whatever we get paid, it's way too much...

But you'll never have the thrill of straightening your index finger and applying just the right amount of pressure to that button, and hearing that engine roaring into life.
And, just to be sure, it's your index finger...
Did Speedsters ever come from the factory with a starter button?
I know Pre-A speedsters had starter buttons. That's why I had Henry put one in mine.
I installed my new Bosch ignition today. I had to Dremel the hole just a little bit to make it fit. . The original hole was only .73 inches and the hole needed to be .85 inches to make the new Bosch ignition fit. The old ignition was labeled with words and the new Bosch ignition merely had numbers. I had to reference a PDF that lists all universal electrical numbers. I believe it is based on DIN standard 77252. It was pretty easy all in all. The new Bosch ignition is much more crisp and the click stops are more definitive. Also, the key doesn’t come out while the car is running. And most importantly it doesn’t look like the key I use to open my mailbox. LOL

I love mine! And plan to put it in the Coupe 
Looks upside down to me

Damn it! I’ll fix it and see how it looks. LOL
@Robert M : Looks great! No more confusing it with your mail box key now. I’m confused though. Is it Bosch? I’m happy to hear you didn’t drill an “extra” hole for a starter button in your dash too!
Put some holes in those keys and nobody will ever mistake them for mailbox keys again...

The worst part was when I went to open my mailbox and it started up. I realized I was using my Speedster key.
Mans yes, the new ignition is Bosch from Sierra Madre Collection, about $65.00.
Maybe I missed this in the beginning, but:
@Robert M : Can you list the part numbers from Sierrra Madre you used for this switch (pun intended)? Maybe a copy of the PDF you used for wiring as well?
Thanks...

Wiring PDF is a few posts above. You'll see it at the bottom of the post.
@Robert M : Thank you kindly! I found the PDF as well. I realize now why I missed it in the earlier post.
The file name klemmenbezeichnungen.pdf intimidated me a little bit!
