tachometer on Super M

Hi all, I got a "Glow Shift" tach for x-mas from my wife. I asked for it because I read on here is was the thing to
have. I'm not sure however how to hook up the green wire. The instructions call for me to attach it to the vehicle's
tachometer source wire which a 53 super M doesn't have. It has been converted to 12 volt by the way. I thought I was
going to be able to hook it in somewhere near the distributor. Has anyone hooked one up and can tell me what I need?
Thanks for any of your solid gold advice.
 
Assuming our SM the electrics are 12 volt negative ground, the green wire should connect to the NEGATIVE primary post on the coil. Ie. to the coil post that's wired to the distributor.
 
I went through all that back in the mid-1960's! Trying to use an automotive tach on a slow reving tractor engine. Spring of '69 I bought a used distributor drive gear housing, a tach drive cable and a tach for a FARMALL 300/350 and installed it on my stage II Super H. Only took a couple hours to install.

Same thing could be done today also. Parts guy at my IH dealer back then had the drive gear housing set aside for His H but I beat him to the punch.
