It is difficult to answer your question because the answer can easily come out as being rude. Make your life easy if it requires an adaptor, buy the adaptor. Having never worked with your set-up that is the best answer I can give you.

I understand that, but the adapter isnt the issue. 30 dollar part. Its the whole MSD ignition setup thats the problem. I dont currently have it. I just have the distributor.

Is it an aftermarket tach? Most aftermarket electronic tachometers I know of can read a signal off the negative coil post.

Pulled this up on the interweb -- so you may want to check your own resources. 
Red wire would go to coil negative -- as stated before. That's how every other aftermarket tachometer gets its signal.
EDIT: Then again, just found this one on Jeep Forum:
Might take a little more searching...

Found this one here:
Looks like actually coil positive will do the trick. Coil negative may just be with aftermarket tachs.

Well, it does make noise with a little throat in it. I'd like to see those horses pushing your Jeep down the road. Those side dump pipes would drive me crazy. ....... but I'm old.
