Possibly pictures of the distributor will be shared?

I'm using the stock distributor from a 1996 Cherokee.

Any modifications required to the Stock 1996 Distributor?

Just had to change the wire plug. I did the same with the TPS and the IAC plugged in and seams to be working.
I don't have the 02 sensors installed yet so it's running open loop.

For sure . . . the devil is in the details

Dave this system runs two 02 sensors. But the manifold only has one bung in it. Do you think I can get away with hooking both inputs to one 02 sensor?
I just don't want to have to pull the exhaust manifold off again, it's a P I A.
Here's another video of it running.

I'm guessing, but I think two O2 sensors in a single exhaust is mostly OK. I'm thinking GM used Bank Assignments on V6 / V8 engines for Fuel Trims . . . for error codes Bank 1 / Bank 2 rich or lean. Theoretically (I think), both O2 sensors in a single exhaust would simultaneously trigger Bank 1 / Bank 2 rich or lean errors and simultaneously correct to the same rich / lean fuel trims?

What happens when one spark plug fails in the inline 6 with two O2 sensors in a single exhaust causing "All Banks" to run rich is anyone's guess how the engine will perform or cause potential engine damage?
