I have a 96 f150 that has a factory premium sound package. Apparently, this means it came from the factory with an amp. So I have two harnesses coming from the dash board that plug into the factory radio. One is a square, has 8 wires and are for the speakers. The other on is elongated, and has 8 pins in it.

These are the colors of each wire as they lead to the harness and what they should be connected to:

1) Dark Blue - ground
2) empty
3) Black w/light green stripe - ground
4) empty
5) Light blue w/red stripe - Radio illumination
6) Yellow w/black stripe - Switched power (ignition)
7) Black - ground
8) Light green w/violet stripe - constant power (battery)

So I am hooking up the new wire harness for my new radio. The square plug is easy. It's 2 wires for each of the four speakers and just plugs in. For the elongated, 8-pin plug, I have connected 4 of the 6 wires (remember 2 are empty). # 5,6, and 8 above are easy and are connected.

That leaves the three ground wires - # 1,3, and 7. I found a schematic on-line that shows pin #7 (black) goes to "G200 (bottom of left kick panel)". Pin #3 (Black w/ Lt. green stripe) connects to "G203 (Bottom of right kick panel)". Pin #1 (Dark blue) connects to "lt Grn" - there is a word that ends in "lt", but it is cut off the page and I can't see it, so it is "____lt grn".

Of these 3 ground wires, I connected pin #3 to the black ground wire of the new harness (I just guessed - I figured if the other two go to a kick panel, than this one hopefully connects to the black ground wire from the new harness). That leaves the 2 kick panel grounds to be connected and I have no idea what to connect them to.

I plugged in the radio and it turns on and everything, but I have no sound. I'm hoping that someone can tell me where thee two ground wires should be connected, and that will fix it. An ideas?

 

Can you post pictures of your stereo and also the connectors ? Thanks !

 

The dark blue may be an amp turn on wire. The amp should be located below the radio in the dash. #3 should be the ground you use for the radio according to what I found.

 

my stereo wires were chopped off when stereo was stolen...i need a better diagram than what your solution gave a similar fix 1990 ford f250

 

Joegeds I'd strongly suggest buying an authentic Ford EVTM which would be far more helpful and exact than most schematics you might find online.

I PM'd a link to a great find for such a thing-----hope it's helpful!

pretty sure that one of those plugs is for a cd changer. the other should be the audio side of the house. cap the wires to cd changer and just use the wiring schematic that madsonp posted up.

 

this site has the pinout for the stereo wires :
