Install digital dashboard display.

[Evilsmuff]

I will be one of the ones with the wacked or slightly off questions. My caravelle "requires" a few "creature comforts" that I intend to install as time goes by. she has power mirrors, air, tilt & cruise, but i want those pl, pw, and digital display dash. how difficult will it be to pull the wiring systems i need for all and would it be possible to slpice and retrofit for the dash? cheapest ways the best too. no adapters or mechanic shops. oh yes and stereo is not an issue i'm worried about.
