Hi fellas, nubie here. Here's the deal lol. Please, don't shoot me lol I didn't actually do this. Just trying to finish it. Bought a 1983 cj7 jeep. Previous owner decided to ****** the 258 out and set a 1980 ford 302 in it. I'm good with that part. BUT previous owner didn't remove wiring harness then tried his best to tuck the 302 wires in. Needless to say I have an eagles nest full of wires under the hood......
what I'm wanting to do to it is bypass the computer module and have it straight wired up. The old fashioned simple way. Push button start, my problem is all the diagrams I see says I'm supposed to run a wire from the negative side of the coil to the distributor. There s no where I can see that I can run a wire to. It's a mastercaft dizzy, it has a purple, orange, and black wire coming from the pick up inside that go a plug. Should i splice a particular wire and connect it from there? Or is there a trick to this that I'm over looking? How can I wire the distributor to the neg side of the coil???

 

Sounds like it has the stock ford Dura spark ignition module. Search wiring for that. Stock jeeps also used a similar ignition module.

 

Interesting. I'm getting ready to put a 1980 Lincoln Versaille 302 in a Jeep.

If you're using the ford distributor, don't you have to use the ICM? I don't really know because I always convert to HEI distributors. No ICM required. Just the one wire to the distributor.

 

I know of a stock DSII dist. that ran 10's in the 1/4 mile so don't discount the dist.
To use the dist. that is in the motor you will need to run the Motorcraft ICM, the box that is on the inner fender well of the late 70's to late 80's Ford cars & trucks and you can still get them at auto parts stores.
Try this link on how to wire up the box. Start, Ignition, & Carb Circuits - Gary's Garagemahal (the Bullnose bible)
IIRC the dist. harness should go between the dist & the ICM, you can make up your own harness.
The other side of the box I believe would get hooked to the trucks / Jeeps wiring. Think 1 is a power wire, other a ground and the 3rd maybe a tach but check the link for wiring.

Edit: you can also run an MSD box in place of the Motorcraft box and MSD makes a harness between the dist & MSD box.

 

Thanks for the replies.... definitely gonna be looking into the Hei. And I do have the icm. Still don't understand how I'm supposed to run a wire from the negative side of my coil to the distributor. And if I want to omit the computer, what do the 3 wires coming out of the dizzy do?

 

1974/86 F100/350 & Bronco: Module located on the left fender inner apron across from the V8's red hot left exhaust manifold. Modules located in this position tend to burn out due to engine heat

Ford changed the apron design in 1987, so thru 1991, the module is located further back and down on the apron...away from searing engine heat.

1974/79 F100/350, Bronco & Econoline: There are FIVE different modules.

1974/79 Cars: There are FIVE different modules, but two were only used in 1979. One with 4 bangers, the other on 1979 LTD/Grand Marquis 351W with EEC (on-board computer).

Post #3 ~ 1980 Versailles 302: There are TWO possibles modules, depending on where it was sold new. Canada & California use the blue module, otherwise it uses the same module as 1979 351W

Besides these two, there was another introduced in 1981 Passenger Cars, F150/350, Bronco & Econoline.

Modules are identified by a colored plastic grommet located above where the wires feed out. The blue grommet module introduced in 1976 is the most common.

You have to make sure the replacement matches the original, as the wiring is different on most of these puppies.
