well, with work and the holiday and what not i have not been very good about updating...so here it goes in reverse order:
after adding a direct wire from ignition (run & start) direct to the coil (something i had called painless tech support about and was told i didn't need) AND removing and re installing the injectors on the TBI (i must have put them in screwy when i rebuilt the unit long ago) it started right up!!!
that rumble was music to my ears...
anyways, the wiring has been, as you might guess, the biggest ongoing issue. when i originally called tech support at painless the guy told me that the pink wire coming from the computer & harness was the only wire i needed to hook up to ignition (run and start). after consulting the painless instruction manual and the chilton's wiring diagram for the chevy motor i realized that i needed power direct to the coil in addition to the other pink/black wire going to the ecm.
besides that, the other major issues i ran into were:
1) wiring up the brake switch correctly so that the TCC will function properly...painless has a diagram in the back of their manual which is pretty easy to follow and involves adding in a relay or you can try to adapt a chevy brake switch which i didn't think could work on the toyota pedal assembly:

2) the new harness did not come with any park/neutral safety switch wiring or instructions (and neither did the Lokar shift kit) and also did not mention that you need to purchase Painless part # 60122 for about $70 if you want the EGR to function properly and tells the computer when the vehicle is in park or neutral.
currently i am trying to get it back together enough to get it down to the exhaust shop...i put the clutch fan back on it with no shroud to provide some cooling until i get the electric fan mounted and wired...i figure it's cool enough here right now and am hoping i have the temp sensor hooked up correctly to show me if it's getting warm.
