I bought a spare 96/97 engine harness to see what it would take to make a plug and play COPs setup from the square 4 pin connector. After removing the tape to separate it from the injector harness it looks like it'll work real well. The only minor thing is that it sources ground after the connector.

FYI Guys. Since I dont have a dremel I couldnt do the mod to the contacts that Braineack recommends in the archive. Chad recommended I just hack saw the end and bend the contacts down. It was simpler then that, I hack sawed and the contact just crumbled away. Hacking away just what is pictured made a perfect fit in the factory connectors.

4k update
Have almost 4k on the coils now. Interesting update.
Lately it's also not really had the pull I expected at 10+ psi, but mentally I attributed it to the shitty gas blend we got this winter, and my subsequent reduction of timing in boost. Yesterday I entered an illegal contest of speed, and got some misfires at higher boost. Ignition break up at high load is almost always spark plugs, so I picked up a new set on my way home.
Went to intall the new plugs after dinner. Pulled the old ones out, and the business end of them looked perfect, great color, square and straight electrodes. But the top end that meets the coil was fouled with black deposits. I pulled them out and cleaned them with a wire brush on a cordless and put them back in. Car takes off like a rocket again through 15 psi.
A co-worker of mine said he's noticed the same thing with his Toyo coils, and cleans the tops of his plugs periodically.

This is bullshit. I put in my coils yesterday, wired them up as per the archive thread. Try to fire it up and nothing. Just floods. I started with my working MSQ and only changed the dwell and it didnt start. Then I tried fiddling with the dwell settings, crank settings, ASE settings and nothing helps. It sounds like its about to finally start and doesnt. I get spark on all four coils as well. At this point I am waiting to get my other set of weatherpacks to wire the factory coils back in and see what happens. This is really upsetting me and I have no idea what else to try.

Cranking PW's too high.
I started the car flawlessly with new spark plugs and the old coils, let the engine warm up to operating temperature, swapped the toyota COPS back in and it started on the first shot.
I think it has to do with the fact that the COP's require much lower cranking PW's then the factory coils.
Its funny, but I would think with their more powerful spark the car would start even faster with the additional fuel required for the factory coils.
Anyway, I cut down all the PW's by 2ms in the 80-60-40 range and ill see tomorrow what happens.
Edit: Arkmage experienced the same starting problems I did when he switched over to COP's. I just remembered. I gotta see what cranking PW's he settled on.
Oh and the dwell settings def play a big role in the warmth of the coils. running 4.0 vs 2.5 was a big difference to the touch, ON A HOT ENGINE.
edit 2: I did learn something great from this whole ordeal. I changed my spark plugs for the first time ever,I was scared shitless the whole time but Chad was holding my hand.

I don't know wtf a cranking PW is. lol. Is that a MS thing? Is PW pulse width? What is the pulse width when the engine is running? Set it to that. I would imagine it's the same as your dwell. I don't think I have that in the ems.
I wrapped my wires in electrical tape. It almost looks oem. You could toss some split loom tubing over it. Maybe you could cut notches in the mounting plate and hide the harness under it. =)
