Anyway, I'm nearly done the rear mount, but the neighbors yelled at me for grinding so I had to give it up for the night, sadly. I'm pretty proud of what I've whipped up so far so eventually I'll show you where it's at now and then hopefully again when I finish.
I'm gonna get out for a snack break now, but first a question!
Spent the last hour and a half tracking down the issues with the ECM, it's not getting power. I've determined that if I run power right to the main ECM power pin (B1) it (and Will's loaned SGII) work properly, as well as the immo stuff. So, what's the problemo? Grounds? I think I've done all the multi-body grounds inside the car, but are there grounds hiding around the engine somewhere I need to tackle?
Thanks!

Does the wiring still have/use a main relay? (The thing that used to be in your left kick panel behind the dash) If it is, take it apart and re-solder all the points on it. If you need to, you can run the ECM on a switched lead instead of it's original wiring (I've had to do this before on the Civic.)
I wouldn't jump on grounds immediately for this one, instead, trace the wire from B1 back to wherever it terminates in the harness and every foot or so, check for voltage w/ the power on. At some point, you may find a short or open circuit.
The only ground that ever (normally) effects how the ECU operates is the one directly under the dash on the d-side, and the one that connects to the thermostat housing. I'm not sure what part of the harness you've reused, so you'd want to look into all the grounds (clean the contact point and the terminal with a wire brush) that you have used. Also, you may want to make sure the ECU is grounded (case) before you really get to playing with it, I've destroyed more than one by not having the case clipped to the body of the car.
Also, regardless of whatever engine grounds already exist, I'd still make sure there is one from the battery to the head, batt to block, batt to transaxle, batt to body.
Remember, the easier pathway you have for grounding, the less electrical load you have to deal with.
