I have a High Sierra, but it's not electric and it's from the early 80's. At the time the only other mtb at the lbs was made by Univega.

To help you out we'll need a lot more details about your bike. Pictures would help, including of each electric component it has on there now.
No way for me to know if these are similar to yours, but there's an old thread about an electric Schwinn Sierra:

Chances of finding factory new OEM anything for it is nealy zero. Send us a picture of what you have, and we can try to figure out what bits are missing.
If old pics exist of it on the net, you can search for them as easy as we can. It's not something so common we recognize it by name. But it's highly possible the motor and such on your bike is extremely common. It could be a currie setup for example, which parts can be found for. Just not "branded" shwinn is all.
Looks like I searched it already anyway. http://endless-sphere.com/forums/viewtopic.php?f=3&t=44458
Now we need to see your bike, to see what remains of the 24v currie motor system.

It could be a limiter for the top speed of the motor. They had something like that on the old version of R-Martins R-10 mid drive. When the bike would get to full speed the controller would cut power until the bike slowed down to a certain speed and then it would turn back on. If your bike has pedal assist it may also be a sensor for that or somebody used to have a wireless bike computer on it.

Most likely a pedelec throttle. It would detect your pedaling, and give some motor when you pedal. A crude system, many much prefer a plain handlebar throttle.
I believe it's a Currie type ebike motor system, so look at scooter parts outlets, ebay, and such for parts that can be made to work with what remains on your bike.

Here's a list of scooter parts web shops:
electricscooterparts.com
monsterscooterparts.com
tncscooters.com
thesuperkids.com
currietech.com
TNC has about the best prices from what I've seen. Currietech and thesuperkids are kind of expensive. Currietech also seems to be out of stock most of the time.
If you were to post a list of the parts you need or maybe some pictures we can help you find them.
