Does anybody have any wiring schematics for a 2000 F-350. I would like all that I can get but I really need the one for the radio. only 1/2 of my speakers work and I am thinking it is a ground issue.

A bad ground will not cause half of your speakers to quit. Which half of them are not playing? Left, right,front or rear?
Battery LIGHT GREEN/ PINK (+) RADIO HARNESS
Accesory BLACK/ VIOLET (+) RADIO HARNESS
Ground BLACK (-) RADIO HARNESS
Illumination LIGHT BLUE/RED (+) RADIO HARNESS
Power Antenna AMP=BLUE
LF Speaker (+) LIGHT BLUE/WHITE
LF Speaker (-) ORANGE / LIGHT GREEN
RF Speaker (+) DARK GREEN
RF Speaker (-) WHITE/ LIGHT GREEN
LR Speaker (+) TAN / YELLOW
LR Speaker (-) GRAY/LIGHT BLUE
RR Speaker (+) BROWN / PINK
RR Speaker (-) ORANGE / RED
Amp Location BELOW RADIO

My right front and right back aren't working. I thought it might have a separate ground on that side. It is looking like the speakers don't have grounds and that it is probably be my radio.

Have you checked the balance control on the radio?

The balance control is good. I have been messing with that. When I switch it all the way to the right side it doesn't do anything. I just put a test light on the wires on the back of the radio on the left side speakers and it is nice and bright. I then put the test light on the right side and it is very very dim so I guess there is something wrong with the radio. I took it apart the other day and didn't see anything obviously burnt or anything.

Did you recently change out any of the speakers? Did it start out an an intermittent problem?

I was driving down from Alaska and the RR quit working then maybe 2000 miles later the RF quit. I have swapped speakers to the other side and they worked.

Do you know if there is a factory installed amplifier in the truck? The only thing I can think of that would have the speakers go out one at a time, would be a bad solder jount either on the output chip or the plug in which the harness plugs into. Or somewhere between the 2. Have you tried removing the radio and physically moving the harness to see if you can make the speakers play?

I didn't change the speakers out either.

I don't have an amplifier. The whole system is still factory. I have taken the speakers out and hooked them up to the other side so I know the speakers are good. I have taken the radio out and looked at all the solder joints inside of it. I have wiggled the wires on the plug on the back of the radio and I am not even getting scratching noises. Nothing at all is coming out of them. I did find one plug that the wires go through and then out to the doors that is located under the glove box. I took it apart and cleaned it with no luck.
