Went back today, pulled the smallport throttle cable and fuel line, so I'm good for now. But thanks for the offer / help, Donald!
I also grabbed all of the cruise control stuff, or at least I tried to. I'm going back again to get a few more parts. I'm hoping some of this will be plug & play with my All-Trac. There are a lot of unused connectors here & there under the paneling.
I also grabbed the bigport FWD thermo housing, since it looked a little different than the Prizm smallport housing. It's different, but not by much! The main body of the housing is almost identical to the smallport housing, with some sensors added or missing (depending on which you're looking at). The water neck for the radiator hose seems to be the only thing really different. So now I just need to track down a GTZ FWD (GZE) thermo housing (good luck to me, lol) -- if it does indeed have an E series tranny -- or hope that the GZE MR2 housing will sit properly on my tranny. I know the GZE powered MR2s have E series trannies...

After I was done gathering cruise control bits:
I spent HOURS carefully pulling apart wire loom, inside and in the engine bay. Holy cow. I don't ever want to have to do that again... but I know I'll have to someday
I still ended up doing what I didn't want to do, which was clipping wires since there were points at which I just couldn't undo any more loom, without pulling fenders and that sort of thing. And by those points I was tired anyway...
