Hello. I think these are what you're looking for. Looks like you're in for a job. Hope it helps. Let us know if you need anything else.
Edit: I would have to agree with Steve. The easiest way to do this would be to get the OE pigtail and wire it up. Simply match colors and you'll be golden. Then if you want to add an aftermarket radio, just get the adapter from Amazon or wherever else and plug and play.
