The harness' connectors are all LS engine specific, so you are kind of implying that the project uses the LS sensor package adapted over to another engine. That could be done but gets expensive / tricky pretty quick.
If you're thinking about running different sensors / hardware but using the GM harness with new connectors on it, sure, could be done - though I'm not sure how much time and effort you are going to save. You can't use the GM computer without GM cam & crank sensors, which as I said gets tricky, and cutting the GM computer connections off and wiring them to some other controller is a lot of work just to save a few bucks on wire.

Have you looked at Megasquirt?

People have done it by adding crank/cam wheels/sensors using various methods.
I am not aware of an AMC engine that has utilized an LS computer.
Could be done though.
You would need to add a 24x crank wheel, and 1x cam wheel.
Or 54x crank wheel, and 4x cam wheel, if using later pcm.

I have begun investigating doing the swap, I believe using a stock GM 24x crank wheel and fabricating a crank sensor mount is doable.
Just haven't begun mocking anything up.
It appears size wise that the wheel would be large enough to mount on harmonic balancer.
I also believe that a 1x wheel from a '96-ish 5.7 Vortec distributor may work on a modified Duraspark. But again haven't started trying to mock one up.
There is also an individual who creates hybrid distrbutors for ~$150.
He basically uses AMC base and GM top, he has done AMC/TBI this way and when I spoke to him he didn't think using a later one would be any harder.

Adapting an LS package to work on an AMC would make it run better but it's a more complicated solution than necessary, and you still don't have an overdrive transmission. Easier, I think, to LS swap it OR go with Megasquirt, an AW4 trans / flex plate (crank sensor mounted to bell housing, reads flex plate) & modify the distributor into a cam sensor if you want fully sequential injection / spark. Easier still to run semi sequential + waste spark with just the crank sensor.
Then you have overdrive, pretty simple physical modifications, and it's easy to tune as the franken-motor that it is. Just add throttle unit of your choice.

No, he isn't, but if he's asking about putting an LS control system on an AMC then he should be asking about it.

So the crank trigger would probably be the easiest there a couple aftermarket companys that build a external sensor. it's the cam sensor that would be the hardest part but I feel like it could be done

Take a look @ this thread.
http://board.moparts.org/ubbthreads/...1376544/1.html

Some decent pics, like I said people have done it on non chevy engines.
I have been slacking on going to JY to snag a vortec distributor, and see about converting a stock duraspark.

If you search for ls conversions several threads out there. I haven't seen anything AMC specific, but I believe it could be done.
