Overhead Console Wiring Questions

I have purchased a Overhead Console for a 98 Venture
With the Compass / Fuel Computer.

Can any one tell me where is a good source for the wiring harness
info on what I would need & if it would already be installed from the factory? (I currently just have the "Light Group" console)

Thanks

I've been looking into completing this as well. Is this modification possible with the base model Venture? I have a 2004 Venture Plus?
