Just an update. The car starts and runs with the replaced resistor and coil wires switched. I am installing the wideband, and hopefully can start tuning in earnest soon! This time, I think maybe I can keep all this stuff installed and not go back to OEM to drive it. :D
Suggestion on which wires to switch on the harness to change the coil output so it's in the same arrangement as OEM? I can do it on the MS unit, but would rather change the wires on the harness. I had trouble trying to guess from the picture on the sticky.

No I mean the db37 harness. The spark plug wires are fairly obvious, even to me.

Swap the green and brown wires going to pins 31 and 36 on the DB37.

Thanks Braineack and Reverent. It's nice to get past this point and get back on track. This has taken too long.

Yeah I guess I knew that. After posting, I remembered to look at the excel diagram you sent back in April that had it laid out. I switched the wires.
This has become such a drawn out endeavor that I forgetting stuff faster than I am learning. I should be used to that at my age, but this is taking much longer than I had hoped. I'm losing focus and enthusiasm with the slow process. A little apathy was developing too.
With 2 kids in college, 1 teenager, working 12 days on and 2 days off, teenage son in sports, the rare vacation, maintaining an old house, struggling to have a minimal social life, I only seem to have time to look at the car for a couple hours here and there about one weekend in the month. Previously I would put it back to stock to drive it again as it's the preferred DD.
This being the weekend, when I get back from the football game later and after mowing the lawn, I should finish getting the MTX-L wideband in. I'm running the wiring through the shift boot and spliced its ground to share with the MS. I hooked up to the switched radio power and all I have left to do is find the headlight power to attach to and solder onto the wideband wire of the MS and I will be ready to calibrate and plug in the sensor to the downpipe! I bought a new O2 sensor socket and Friday I unstuck the lousy stock rusted-on O2 sensor that absolutely wouldn't move for me at home by getting it up a friend's lift to breaker it loose without destroying it since I needed to drive it home. Since Saturday morning I've been driving with the MS in, and it's running rough and untuned so I am very ready to start tuning with the wideband in place.
This is a critical time as I want to get this step done and have the car drivable by the end of today. I probably won't be able to do anything mechanical for at least a week. I'd like to get the tuning started asap.
With this progress, probably in the next weekend or so I will put in the the new fuel injectors. If all goes well with the electronics, I will start refurbishing the turbo parts and figure out how it all goes together to attempt the installation probably in October or November. I am beginning to get excited again! :D
