GM Delco Bose Wiring Diagram

Why is it so hard to find wiring diagrams for gm delco bose systems? I have been looking all over the internet for a month and all I can find is your standard wiring for gm cars, yellow is power orange is memory and so on, why can't I find any diagrams for the amp wiring, my bose amp has an eight pin plug and a 24 pin and I have no idea how to hook it up, does anyone? I have a 1994 Lumina Euro that came with a standard am/fm cassette. A bose system was a option and I bought one on ebay. It is a bose silver series head unit a u85 bose amp and bose speakers, however I did not get the wiring harness with it. Can anyone help me out?

Probably because nobody does that...! What did you pay for that...?M.E.C.P & First-Class

Go slow and drink lots of water...Procrastinators' Unite...Tomorrow!

With everything I paid around $250.00. I would still like to find out how to wire it.

If you are willing to do a little footwork with a meter, I can at least help you identify the speaker outputs and power and ground wires.

I don't know which wires are the input to the amp from the head unit. Power to the amp is easy, it's a big fat orange wire and a black wire. The inputs and outputs are the same size. I can't believe that there is not a schematic out there somewhere.

you can find the wiring in the factory service mannual for that car.  Maybe Mitchell too

The head unit is out of a 1994 lumina. The amp has a date of 6/21/00. The numbers on the amp are 10440936  2W A00  U85  Amp Assy,3630G,WPONT if that will help. I am pretty sure it was a 6speaker system because I got all the speakers with it. one time I was on a Pontiac Forum site that had the diagram, But I cant find it. The Lumina is nice and I want to keep it original, and the factory radios work well. I can install a jack in it for ipod,mp3,ect. Thanks for the replies. 

I can do the meter test but I don't understand how we can identify the inputs to the amp. Thanks
