Help on bypass (merged)

Trying to so nutter bypass to 1989 wrangler 4.2l, I cannot figure out what happens to the purple wire. The orange ends up turning light green when going to ignition module, does purple change color or what?

From Joe Peters and well stated. Sounds harsh but just makes sense:

“Let’s play a game.

You pretend that you are the only one that knows what year/engine/model, etc that you are asking about.

We will all pretend you never asked a question until you provide at least the bare minimum of information about your vehicle”.

Ding, ding! We have a winner! Haha! Sorry, that would've made it to easy on it. Yes, it's 89 wrangler 4.2l 258. As you probably suspect too, I'm trying to do the bypass. Again, sorry for the lack of info. I was at work trying to type quick so I didn't get caught on the phone.

Here is a link to check out: http://home.sprynet.com/~dale02/ignmods.htm
Click the images to see more info.

Essentially, the purple wire from the distributor gets spliced into the purple wire in the 4-wire ICM plug. The correct wire on the ICM side of the connector will be paired with an empty slot on the harness side of the connector.

Optionally, the empty slot in the 4-wire plug is where you can plug the purple wire from the dizzy into the ICM, provided you use the right weatherpack pin. So, instead of going around the 4-wire connector, you make use of the connector like the factory CJ setup. This is how the computer bypass is done for the Howell TBI kit and lets you disconnect and remove/replace the ICM later without cutting and resplicing wires.
