Your best option is to go the NCE's website and look at what they recommend for your application.
I am not sure what the URL is, but keep in mind, the proper name is North Coast Engineering. They have a lot of application info on their site, and will probably have several options that will work.
Another great place to look up decoder installations is Train Control Systems web site. They have installation pictures for almost all the popular locos on the market.

Please take some friendly advice and test ALL locomotives on DC with an ammeter before installing a decoder. A bad running loco will still run bad with a decoder and I have seen too many disgruntled people that have fried decoders because of amp draw or miswired installation.
Hope this helps
