Wow jsut saw this... I did this about 7 or 8 years ago but was to lazy to do a write up.... Just love the MP3 input.
I know this is an old post but it’s proving SUPER helpful!!! In the aforementioned fused wire jump. What size fuse should it run?Here are the wiring mods you need to make:
Below is the main power connection. plug on the left is the AMP Harness plug that comes off the 1993 amp harness you just installed. Plug on the right is the body harness in your car. Got it? Good..now notice the differences in wiring.
Looking on the body harness side, we have the following wires
green/yellow - constant 12V
yellow/black - accessory 12v
blue/red - dimmer
orange/black - illumination ( i beleive for the bulb in the display of the 87-92 radio)
RED - GROUND
The orange/black wire is not needed anymore with the 1993+ radios, so don't worry about it. But notice that on the amp harness side, there is one wire not connected to anything. The white one?
That's the AMP Power wire...kinda important. As you can see, it's not connected to anything. According, to the 1993 Mustang EVTM, it's constant 12V. I don't really want the amp powered 24-7, so i jumped a fused wire from the white wire on the left, to the yellow/black wire on the right.
And that's it...one jumper wire and you are good to go.

The speaker colors are all mixed up, but don't worry. I spent an hour tracing them out with a 9V battery to be sure...they match up fine. HOWEVER, if your 87-92 Mustang is a non-premium car, you might lose the door speakers. They are wired in parallel with the dash speakers. In that case, you will need to run wires from the doors and tap into the dash speakers. More on this in the SPEAKERS post

thanks!
I found the same radio. I bypassed the factory amp and plugged it in. Everything powers on, except the display reads "tape". This confused me because there is no tape player on the radio. I for some reason cannot get it to switch to AM/FM. I think i got a defective radio. I don't believe there is any kind of reset to make this switch to AM/FM. I will be returning the radio to the ebay seller. Its a shame, it arrived in a factory sealed FORD box. It has never been use.I know this is an old post, but it helped greatly in my decision to install a newer factory radio into my 1991. I got a non-premium standard Cassette deck from a 1995 Escort. It has the correct trim for correct fitment into the fox mustang. Ford F-150 & bronco also have the correct trim just FYI. The OP was correct on it needing a second ground for the night illumination to work. On the grey plug, wire 7 is not in the plug on the 87-92 mustangs because it is not used. All you have to do is add a wire to your current plug (i cut the harness off the car i removed the radio from at the Pick your part & took out one wire and added it to my connector) I then connected it to wire 3 which is also a ground. Works perfectly. Night lights and dimmer. I used the Cubby from my factory 91 radio and just switched radio bottoms, I also found a non cassette only am/fm that also worked, thats pictured. Kind of like the look of the non cassette.

First thing I tried was hitting an/fm. Then I tried a million key combos thinking it needed some sort of reset.I wonder of you popped that face plate off if you would find a tape deck?
Hitting AM/FM should take it out of tape mode if it was a tape deck.
I ended up grabbing another radio from the junkyard out of a 1992 taurus. This time it had a tapedeck. worked great for a few days and then it started going back and forth from am/fm to tape on its own but just for a split second. Then i started to think, do I have some sort of short? At one point yesterday, it went from tape to "TELE" which I have never seen before. I didn't even think that was an option in 1992. After I turned the car off and back on everything went back to normal. It no longer does the tape to am/fm thing and I have not seen a TELE since that one time. Just wanted to share my experience since it seemed somewhat unique.I’ve pulled a bunch of these radios apart (in an attempt to learn how to repair them as I have a few 93 CS players to repair) but I don’t think there is interchangeable components. That’s why I’m curious on the internals.
Of course if you are returning it I wouldn’t bother disassembling.
@Mustang5L5 I've put a picture on here of the amp end of my 1993 Mustang Premium Sound wiring harness connectors. Which illustration/s above are these connectors? Do I have to use a '93 Mustang Premium Sound Amp or can I use one from a later Ford like F150 as long as the connectors are the same?
