I have an 850T and I can't for the life of me find a way to get my radion to stay on. Every time I place a new fuse it emediatly blows out. I also have what looks like to me a red remote wire that, I guess is supposed to go in the same place as the fuse. Is it some thing that the previouse owner might have rigged up. Is the 850T supposed to have that remote wire going into the spot with the fuse in the fuse box. Again it burns out every time. All of the other fuses are ok just the one for the radio. Sometime I'm able to get it to work only to hit a hard bump in the road to have it short again...AHAHAHHAHAH

My red wire was for a phone. Take the red wire off the fuse and make sure the fuse is seated correctly. The metal tab has a tendancy to widen the slot for the fuse. Look under the dash by the steering wheel and follow the red wire, mine was cut when the phone came out. Yours may be touching the seat rail causing the short.
There is no extra wire for a stock radio.

The fuse is doing its job and probably preventing a melted
wire (or worse). So, you need to find the source of the electrical
short. I suspect the red wire you see is one someone slipped
under one end of the fuse as a 12V power source. The good news
is they apparently placed it on the correct side so the power
is fused (if it is on the other side of the fuse then it would
probably have melted by now). I suggest you find out what the
red wire is for. Try disconnecting the red wire and see if the
problem goes away. If it does, there is the problem. If not,
then the radio is probably the problem.

Do you have any idea what the red wire is for? Is the radio a
stock radio or after-market (possibly with an amplifier somewhere)?
Any after-market fog lights or other lights?

If you don't know volts from amps then maybe have a car stereo
shop have a look at it. They typically deal with adding after-market
equipment and often see jury-rigged setups like this that need to
be cleaned up a bit. Visit during a weekday (when they are slow)
and they might be inclined to only charge a minimal fee.

Thanks for the info. The radio isn't aftermarket it's the original one that’s what's scary. The red wire seams to be the trigger to power up the radio. If I don't feed the red wire to the fuse it will not come on..

Thats a bit odd. Perhaps it had an after-market setup and the
stock radio was put back. I'd disconnect the red wire and then
pull the radio out to inspect the wiring behind it. To do
that push in on the two tabs at the botom corners of the
radio (use a coin). They will pop out (they are mini handles).
Pull on the two handles to pull out the radio. Then you can
visually inspect the wiring behind it for any obvious electrical
shorts. Stock, there are just plug connectors that plug into
the back of the radio. They are typically wrapped with some
foam to prevent rattles. So, you should not see any cut and
re-connected wires, electical tape, crimps, wire nuts, etc.
