Hi everybody,

I'm John and I'm new here and have a 1990 MPV and an '08 Mazdaspeed3, what I need is a wiring diagram to the stereo system on the 1990 MPV. I just removed the stock AM/FM cassette to put an aftermarket CD player in. The issue I am having is that all the online diagrams I've found don't even come close to wire colors that I have, and it's all original, never cut wiring. I have 6 stock speakers (2 in dash, 2 in front doors, and 2 rear panel speakers), all the diagrams I see are only for a 4 speaker set up. The stock stereo had 2 clips, one with 4 wires going to it (I didnt cut), and another with like 8 wires. I need to know everything (power wire, constant, ground and speakers). And also what this second clip is with the 4 wires going into it.


Thanks for any help.
