The one in the white Tercel that I swapped came off ebay, the owner bought it so I'm not sure. I might be able to get one for you, you can also check
www.gspeedcorp.com and
www.venus-auto.com. That Tercel stayed auto, normally I get my manual conversion parts from local junkyards (Tercels are usually easy to find), offf car-part.com, or off the forums. There's a list in the engine/performance section on this site, a thread written by yours truly detailing everything you need.
For the wiring, actually doing the wiring harness conversion is really hard, take my advice and send it to me, it's worth every penny, lifetime warranty, etc. $350 all done instead of months of headache and maybe having to send it to me anyway. The "wiring supplies" listed there is extra wire, solder, flux, shrinkwrap, looming, tape, etc.
The old engine and tranny I did sell, they were old but still running well, I think I got like $60 for it. If yours is shot then I wouldn't even sell it, just bring it to a junkyard and give it to them.
Moved to Dr Tweak's Garage.
