Hi, I am new here and I need help. I just acquired a 1990 Mazda RX-7 GXL and I need to know what the wiring schematics are for the stock radio that is in it. I have a Sony MD deck that I want to put in but at first sight I see that the stero in the RX-7 is going to leave a pretty big space after I put the MD player in. I am relatively new to the RX-7 scene (this is my very first one) and would welcome any advice/solutions. Thanks!

 

You will need a kit. The best kit I have found is the Crutchfield kit. It is 2nd gen specific, unlike most of the "one kit fits all Mazda" kits.
Also, I would recommend a harness too, unless your car's stereo wiring has already been "molested".
If so, email me direct, and I can scan the info for you.
By the way, I have had 2 MD units in my RX7's over the past few years...a Sony MDX-C670, and an MDX-C5970.
Attached is a picture of the MDX-C670 in a Crutchfield kit (for 86-91 RX7).
Please email me direct if you have any specific MD or RX7 stereo installation questions. I have had several RX7s (since 1995), as well as no less than 7 MD car decks, that I have bought, sold, or installed in the past 5 years. I should be able to help.

 

To take off center dash console, take out ashtray, unscrew 2 screws in the back.

Then there are 2 screws behind the vents up top. they are angled 30-45 degrees. Take the vents out so you can get to the screws. a flathead screwdriver will pop them out easily. From there, it's cakewalk.

Careful to not break anything. Mazda made our plasic stuff reallll brittle. THANKS MAZDA!!!!

 

Hi Paddy,
i have a '86 GXL that i keep in original condition. The cassette on my original system is going quirky and i'm looking for a replacement. Is yours in A-1 shape? If so i would be interested in it.
And Re is soooo right that plastic beauty rim is very easy to crack. Approach it gingerly.
