Mx3 stock stereo wiring to new head unit

Letters11 · Post by **Letters11** » October 13th, 2009, 8:26 pm

Hello all,
I have a 1995 mx3 and it still has the stock cassette player in it. Im still working on getting that thing out of there but i was wondering what is the easiest way to get the correct wires for my aftermarket head unit. I searched around and counldnt really find anything of the same nature but i will keep searching this site. I was looking on ebay and i saw some wiring harnesses for around $6. Im not sure what i need to get my head unit to work. All help is appreciated. Thanks in advance.

Just get an adaptor from walmart or best buy, it's straightforward

The harness chart for the car is on here somewhere, search for it.

then its simple mix and match!

The harness I have even has the component written on each wire (ie: rear left, right front, battery, etc.) and they are color coded.

That chart is WRONG!

blue/white can't be three things at once.
