Alright So I just bought an 89 Wrangler that runs fairly well with a bad clutch so I'm replacing that. While I'm waiting for parts I decided I would go online and look into the Jeep I just bought a bit. I got hooked on a few engine upgrades that were out there mainly the nutter bypass, and the TFI/ TeamRush upgrades. I also plan on throwing in a MC2100 carb too while im at it, or at least a rebuild kit. Anyways so I finally had time to look into the nutter bypass & TFI upgrade only to find that I had a few strange things going on with my engine. The owner before me seemed to have already completed both of these upgrades in some way, but he left a lot of loose ends (literally) there are wires hanging all over the place in this thing that go to absolutely nothing. Very messy once you dig into it. SO Here are some pics I took and I wanted to see what all the pros know about what I got going on in my Wrangler.
First up is the distributor setup. After a little research I'm fairly sure it the HEI upgrade hes got on here. My only question is whats the advantage/disadvantage with having the coil in the cap? Also the plug wires hes got on here are terrible so any plug wire recommendations? I'm also going to throw in some new plugs but which ones would I need with the HEI?
-The first one is a front top pic of the distributor hes got on it.

-Now the internals of the distributor.

The next part is the wiring. I'm pretty sure he did the nutter bypass but the end that plugs into the distributor on the orange and purple wire pair was just laying in the engine compartment not connected to anything. The other end that is supposed to go down by the ignition module was just hanging there not connected to anything either. So the purple and orange twisted pair bypass wire is connected to absolutely nothing. That doesn't sound right to me unless the HEI has no need for the nutter bypass? And what exactly does the nutter bypass do?
-Orange and purple wire pair and plug that is supposed to be connected to the distributor. (sorry for the blur)

Then the ignition module.

The final question I had was what carburetor is this, stock Carter?

Anyways just thought I'd come to the people who know a thing or two about Jeeps. So fire away and let me know what I got so I can figure out how/what to work on it.
