Ok, I have a 2001 Mazda Protege. I bought it used and the original mazda head unit was removed for an aftermarket cd player. Whent the guy sold it back to me, he gave me back the original head unit but no radio harness. I bought a new harness off of e-bay, but I don't know what wires go where and I can't seem to find the wiring diagram for a 2001 Mazda Protege. I can only find up to 2000 mazda protege and then it jumps to the 2003 mazda protege. I tried wiring it to the supposed standard mazda pinout that I found on the mazdaspeed forums but that doesn't work so I was wondering if anybody has the pinouts for the wiring harness if they could post it for me, that would be great.
