I got a free Currie wheel... now what?

So I got this TranzX Currie wheel in a storage auction and I'm struggling to find the right parts to make it work again. I have a donor bike ready to go and was a (regular) bike mechanic for some time. Here is what I know :

The wheel:
Currie Tranzx 48v 500W hub 700c rim. I think the controller is built in??? The only wire attached is a 10-pin circular style, see below.

The original bike / system:
I have found the same wheel on a iZip E3 Dash with Currie Electro drive display and a torque sensing bottom bracket.

I guess here is my question - what is the best place to find the right wires and display, etc. to set up this wheel? Ideally I'd like the same wires and display as the original bike or something like it, maybe Raleigh? Otherwise, I guess I will need to dig into this hub a bit deeper and try and make a new wiring harness for a generic display.

I'd say crawl amazon ebay alibaba for a controller with the same connector. Good luck on the picture being big enough. If the controller comes with a display buy it, if not you're out of luck.
The three motor winding wires will be zero ohms to each other. The three hall effect pickups have a diode drop in them. There are a plus minus to the hall effect pickups sometimes, usually red/black. That's 8? If the controller is built in there might be 3 wires to a throttle or two wires to a magnet pickup for a PAS.
Resoldering a new harness for another connector is not impossible. The cover has obvious screws you can take off. Getting the spring over it is a *****. New connectors tend to come in packs of 5000 from ali with no description or dimensions. this ali/ebay electronics market is a real ****shoot, no dimensions, no description, both sites are crawling with rejected parts. I like real parts from newark/mouser/digikey but they don't sell ****ese bike parts. Mouser listed some XT60 connectors but didn't deliver them in 4 months so I cancelled those and the other $90 of parts on the order too.
A whole new wheel that is not a takeoff with a controller throttle & brake handles was only $189 when I was shopping ebay last year. About 2 hours of fiddling around would convince me to spend that much. The 6 pin rectangular connectors are kind of standard and allowed me to swap the DD motor out for a geared hub that I hated the controller of. PAS 1 was too fast and acceleration was minimum 500 W.

Do you want to sell the hub motor?

I don't think a generic display exists. They all have ther own digital protocols specific to the controller they were designed for. If you found that IZip used a torque sensing BB, you probably need the same hardware too.

While it sounds like a nice package for free, I wonder if your wallet would be better off just finding a conversion kit that has everything but the battery. Sell it to Joe Sammy, for instance,

I doubt seriously the controller is built in.

You probably want to shop for a controller that comes with a display and other misc parts (like a wiring harness and brake handle that shut the motor down when pulled) as a "kit".

Then be prepared to match the controller wiring to your motor - without smoking anything. Not for the faint of heart!

As Harry suggested, you might check the prices of an entire kit, including hub motor, vs. the price of a kit minus motor. Might save a few bucks, but not a lot. This would be something you might want to tackle for the challenge because you enjoy messing with this kind of thing.

Thanks everyone for your feedback and advice. I came across a LBS that sold me the rest of the parts I needed. ... but threw in another wheel for my trouble. So I still have a "free" wheel to fiddle with. I am going to try and figure out a DIY solution since the LBS also said the parts are no longer available. At least now I have an example harness and diagram to follow. Probably an upcoming winter project :)
