Did this to my old ass '94 buick century a while back but it's a cube somewhere now
have this swank ass falling apart '97 Buick Lesabre (yes I'm a grandpa at heart)
But I want to hardwire an aux jack. The cassette player is already fucked mechanically anyway, so - and this is how I did it before - i'm just taking the leads on the connector from the cassette feed itself and wiring it to an 1/8" switched jack and a toggle to go between aux and back to radio/ CD. This "newer" model Delco radio has two more wires than I am familiar with and colors all crazy like.
Anyone have any clue what these wires are? L, R, 12v, etc.?

I found a guide I used with my older stereo that had a 5 cable connector here:
