will it work on an auto 2.4 cavalier. Pics of install are needed

Yes it will. Whether your vehicle is auto or manual is irrelevant. I just recently removed mine due to it malfunctioning. Originally, I got the wiring diagrams off NYjbodies.
It'll work.
This is where I located my MSD DISII box. I didn't have to add any wire to the MSD box with this location and installed a dedicated hot and grounding block so I didn't have to run the hot/ ground to the battery.
On the actual wiring of the connections, I just followed the instructions of the product.
If you need the information on which of the ICM wires to hook up or which wires are the 1/4 or 2/3 trigger, I have that information if needed.
I'm also running external DIS coils on my 2.4. Much easier to work with for the MSD DIS system.

Thank you Dave and JBO! 
ok kool i will need instructions cause i have no clue how 2 wire it up cause im buying it used and i know the box works cause it was on a 96 sohc neon and that damn neon kept up with my car with the box in and then when he took it out i killed him

I've run a full MSD system on a different vehicle, but I've found a wiring method that worked great. But first, what's the Max amp output of your alternator? The reason I pose this question is that capacitive, multi-strike ignitions eat amperage BIG time, and the more total amperage your alternator can put out, the better off you'll be. I speak of this from the teachings from a former "Mr. Norm" auto electrical serviceman & my own experience. The system on my truck incuded a 120-amp HD alternator that I ran the battery positive lead on the box right to for direct max amperage while the engine ran. Should've put a fusible link in-line but still got good results: 20% increase in mileage & an engine that started in half a rev. When the tired, old alternator quit, I replaced it with a 90-amp model that just wasn't enough. When I finally gotta 100-amp Denso model on, all was well & back to performing as it was. So, in short, make sure your charging system is up to the task, putting out at least 130-amps in your case, and wire the box like I mentioned and you too will have great results.
Go beyond the "bolt-on".
You don't need a huge alternator to run an MSD ignition.
With the MSD only drawing 15 amps at max pull, your battery is your reserve for any extra current you need, and won't pull off of the alternator.
The MSD will work with as little as 7 volts but works best in the 11-17 volt range.
It also states that the MSD unit only uses an average of .7 amps per 1000rpm so do the math and you'll see that your stock alternator will work fine.
Coming from 30 years in the electronics industry, 20 years as an electronics tech, and being in the car audio/ home theater industry installation for the last 18 years, know what works.
Just use the factory wiring that came with the MSD unit and if you have to lengthen the wiring, just go one size bigger in gauge.
You need a very good ground though and would recommend to do your own grounding kit or buy one to increase your grounding potential in the car.
Nickelin Dimer, I'm knocking what you're saying but to have to spend money on a huge alternator is not necessary.
So please don't take this the wrong way.
Good luck with your MSD install.

Stock alternators put out about 115 amps, there are some out that put out more though, but beware of ones that do so at high RPM ranges. They may only push 80-90 at part-throttle.

An MSD ignition alone won't make a difference on an otherwise stock car. Don't be surprised by the lack of gains with JUST the MSD box hooked up.
It's a great addition to OTHER mods.... but on it's own it's nothing special.

just installing the MSD box on my car improved my idle and my 1500-3000rpm 10x, really nice mod.

Ok, then you'll actually be able to retard your timing properly (like you should be doing) with the nitrous

Is there a way to wire up a DIS-2 without using the stock ICM?
can you eliminate the ICM and wire this directly to the ECM?
No, because the DIS-2 doesn't replace the ICM... it just makes the spark stronger, and multiple sparks. You still need the ICM to drive the coils.

You need the ICM to drive the PCM.
The MSD will drive the coils.
The ICM translates the 7x crank signal into a conventional tach signal that both the PCM and the MSD will need to function. The ICM also controls switching from base ICM timing (used during starting and some PCM failures) to PCM controlled timing (regular running).
