Pic 1 is all the stuff I pulled out when I installed my HEI.
pic 2 is while doing it.

It seems terribly complicated, but really not too bad.

Look for a post by MudMagnetYJ and look in his signature for a link to several Factory Service manuals. Find the FSM that is closest to your year Jeep and locate the electrical troubleshooting section.
In the electrical troubleshooting section you will find schematics for the emission controls and charging system.
Print what you need and carry the printed sheets out to the Jeep.
Cut away one circuit at a time and then start the Jeep. If it doesn't start and run, re-examine what you cut out and how it relates to the running of the Jeep.

It took me two days of part time work to install the HEI, remove and paint the dash, remove the computer and all related sensors and wiring. At the same time I replaced the heater core because I had the dash out and access to the heater box and computer was easy.

If you have any questions, don't be shy about asking. There is a lot of experience on this forum and lots of folks will help.

Good Luck, L.M.

BUSTED!!!

I enjoyed the beer that was in that bottle.

Actually its a "Clausthauler" bottle. It's a non-alcohol beer.
Classed by the BATF&E as a "non-alcohol malt beverage".

BATF&E should be a convenience store, not a branch of the government.

Good Luck, L.M.

Not yet if you want your Jeep to run.
Once you have the HEI installed all that stuff can go.

Good Luck, L.M.

It was a bit confusing.

Doggone autocorrect.

I took it that you have done the Nutter bypass. ("I don't have the HEI just yet but I have done the Nutter bypass") is how I figured it out to say.

Clausthauler NA tastes good to me. When I drank, I drank Heineken. This is the closest I have found.

American NA beer tastes a bit weak to me. I also liked Ballentine ale but now I forego anything with alcohol in it or any drugs, even though marijuana is now legal here in Colorado. Since I gave up all that stuff, my life has become so much better and (surprise, surprise) I have more money for my Jeep.

Good Luck, L.M.

When you go to install the HEI, keep an eye on the 14ga bright yellow wire and the dk green w/black stripe wire that go to the dist and coil assembly. Don't cut those out. You will want those for your HEI. The yellow wire may be a tad short for the new dist. The yellow one that goes to the ecm will be long enough to drag across the cab if you dont want to have a splice in the line. The yellow is your keyed hot and the green is your tach signal.

I went with the wire that was used previously on the old Dist. rather than add splices, relays, etc. My summit dist instructions "suggested" that the wire would be a 10ga. I have run mine since christmas last year with no problems.

The one thing I like about this setup is the simplicity of the ignition / fuel system. We see new posts everyday on no start issues most of which are stem from some form of vacuum, sensors, electric fuel pump etc. No matter what I break today, I can always count on this beast starting right up. LOL
