It's funny; I used to work on automobiles full time in the seventies, right
when the pollution controls all came out. After working on a few vehicles I
figured, along with a lot of other mechanics, that the damn things didn't do
anything except make the cars run more poorly and use more fuel. Except the
PCV, of course, don't disconnect that. A big laugh was the attempt to use
higher (numerically lower) gear ratios in an attempt to increase fuel
mileage (kilometerage north of the border). The Dodge dealer where I worked
did a healthy business in axle ratio changes, in order to restore a
semblance of performance and economy to his customer's vehicles.

Now with fuel injection this is all theoretically "better", but as Mike
likes to say a properly tuned carburetor performs quite nicely too.

Do any of you have the diagrams for the HEI upgrade? My Chilton book puts
the ignition control module where there is nothing. Picture the book gives
doesn't look like anything under the hood of my 88 YJ. The "directions" the
supplier sent are a watered down version of someone else's vague write up.
The CJ5 and 7's the conversions were done on had way different wiring and
connections. Any current, detailed write ups for an 88YJ withe the 258 6I
would be very helpful.

The Haynes CJ manual is the best one for the engine and under hood
wiring for the 258 YJ's.

The ignition module is 'Waaaaaayyyyy' down under the washer bottle at
the bottom of the fender skirt.

Here is a good site for all things 258:
http://home.sprynet.com/~dale02/list.htm

Here are some specifics about killing that Ford emissions cpmputer:
http://home.sprynet.com/~dale02/ignmods.htm

And:
http://www.off-road.com/jeep/jnutter1.htm

I prefer to add two new wires when bypassing the computer by hooking the
orange and purple wires at the ignition module directly to the orange
and purple wires at the distributor rather than mess inside the
harness. Especially in a YJ, because the colors in the harness are
different than the CJ the article is written about.

Here is an article on the HEI:

Here is a 'great' article on getting that Weber-Carter BBD purring at
idle:
