Dodge Neon Ignition Coil Conversion For The 2.4 (LD9)

Alright this all started out as a simpler, cheaper, yet effective way of removing the 2.4 ignition coils and remote mounting a set of coils. Most just follow with the 2.2 (LN2) coil swap with brand new OEM parts for the swap going for 230, and MSD components for the swap going for 250 and neither of these include the plug wires, unless you can get one cheap out of the junkyard or have a parts car you can't beat my over all price tag for this swap. Brand new Borg warner coil with pigtail, and 96 Cavy 2.2 (LN2) wires making a grand total of 95 dollars. So far no issues have been found, and overall smoother running motor and less misfires.

Parts list:
Ignition coil from a Dodge Neon, Mistubishi Eclispe, or Eagle Talon from 95-newer, with correct connector for coil. (Their are both round pins, 95-99 and flat pins 00- current)
Plug wires of your choice, either 2.2 or cut to fits.
Solider and solidering gun.
Electrical tape or shrink tube.
2.4 ICM and connector.
About 8 feet of 14-16 gauge wire.
The little ground strap from inside the the 2.4 coil housing.
And something to make a mounting bracket out of.
Tools:
7/32 socket and ratchet
13mm socket and ratchet
Wire cutters and strippers.
And what ever tools needed to make and mount the bracket.

Work:
First is to pull the IDI cover with the 2.4 ignition setup out and remove all the parts under the cover except for the ICM, losen the ICM up and slide the little ground strap under it and make sure it will fall between the bolts and cam cover when remounting. Everything removed should look like this.

Now your going to need the connectors prepped and make sure when you cut them to leave enough wire to work with. They Should look like this.

And begin wiring. on the 2.4 connector plug you will notice it is labeled A, B, C. A is the positive feed for the coil and should be wired to the center pin on the Neon coil. Make sure you lengthen the wires as you go. B side feeds coil side 2/3 and goes and C side feeds the 1/4 side of the coil. Here is how the pin out should look.

Crappy diagram for those that need it.

And when all wired, extended, solidered, you should be able to wrap the connections you made and run them inside a wire loom. Here is how it looks in progress.

Here is how the harness looks finished.

Now make sure you label you coils and wires as to ease installation. What ya know another picture. This is how it looks pretty much completed.

Now go out side and run your plug wires, connect the coils to the ICM and remount the IDI cover making sure not to pinch anything, then mount down the coils and connect the plug wires to them and test fire. It may take a minute of trouble shooting to get running, just keep trying. Here is my setup, please forgive it looking nasty I was doing it in the dark, and had to have it together for the next morning as my 2.4 coils went out, this weekend hopefully I can get in there to clean it up. Here are 2 pictures.


And finally my tribute to the 2.4 ignition system.

This write-up is as-is and is by no means 100% and I am not responsible and/or liable for any damages or injuries from doing this. This is to be done at your own risk, and please research any mod before doing it. And testing on this mod is on going and so far so good. Best of luck to any one attempting and feel free to ask me any questions. Untested but may work on a 2.3, again try at your own risk.
Credits Misnblu the great provider of info, Autozone website, and bear8ruf, and anyone I left out. If I left you out feel free to leave your mark here.

Now just get an MSD coil pack, and some good wires, put that thing closer to the Engine, and you will actually have something that increases performance

That is all in time, it had to be finished last night or I wasn't going to work this morning. I plan on an MSD coil and cut to fit wires, but it will probably stay where it is, just do the finishing work to the bracket and such. Thanks for the comments.

MSD's coil pack type coils run 36,000 to 40,000 volts depending upon application per their own catalog. Most stock coils since the 80's run 35,000 to 40,000 volts. If you feel it necessary to buy MSD or any other brand coils, buy a complete ignition system. The factory ICM limits the amount of current to the coils and prevents aftermarket coils from having any positive effect.

On my car, the coil swap made the higher rpm power more consistent. No doubt a result of the stock plastic coil housing leaking voltage. I would consider that a performance upgrade.

I believe it was like 19 inches or something but it is kinda long and had to be tucked around everything to hide all the slack. It would be best to measure with a string and plan out how you are going to route it so you can have an exact measurement of how long you need it.

Possibly got the firing order wrong, I had to try a couple of times. Just let it sit a few minutes after it back fires, swap the plug wires, just remember 1 & 4, then 2 & 3. If you need help email me at Dayton86@gmail.com, and I will try to get back to ya ASAP.

Yeah the firing order is 1-3-4-2 but the paired cylinders are 1&4 and 2&3, and due to the way the coils fire on paired cylinders those are the ones you need to match on the same side of the coils.
