Re: need wiring legend for installation
Sorry...not available, even through manufacturer. Try going to your local car stereo installer and ask them NICELY to solve your issue...the worst thing is a bill for $30-50...If it's free, buy the dude lunch what $10? Good Luck

That's hard to answer cause it depends on how far back on the wire harness they cut. Plus if you have a Bose system or not. I would highly suggest to take it into a stereo install shop to at least check it out but maybe install the new stereo.
There is a wiring color code that all vehicles use but if the wires have been cut to far back they will be different colors. If you have a factory amp then you will have to rewire for the speakers to bypass it.
I added below the color code. Make sure you disconnect your battery before you start wiring anything.
Please note: You can do major damage to your truck computer and other components if you wire it wrong.
Connect each wire yourself if your were unable to obtain a wiring harness to install your car stereo.
Connect the positive wire from each speaker to the positive connector on the back of the stereo first. Then connect the negative wire from each speaker to the negative connector on the back of the stereo. If there is only one wire coming from the speakers, the speakers are grounded at the chassis. In this case you will need to install new speaker wiring.
Connect the ground (-/black) wire of the stereo to a screw or bolt near where the radio is mounted in the dash. Make sure the wire is attached to metal, not plastic or fiberglass.
Connect the 12 constant and ignition power wires (both +/red) to the new stereo. Refer to your stereo's installation manual to make sure these go to the correct places.
(http://inform3.kenwoodusa.com/manuals%5CKTSMP400MR.pdf ) Here's a link to manual and wiring on page 30 on the PDF file. Yellow is constant power from battery, for memory etc. Red should be to switched source.If need be, you can connect both to battery, but remember, you'll have constant power draw on battery when stereo left on but switch turned off, and will draw battery down, if you forget to shut it off, and leave the boat. Speaker negatives to black should work but I would advise hooking my 2 right and 2 left + speaker wires from stereo together, then to one of the speaker positives,right or left for better sound. Fronts will usually supply higher ( high and mid range), and rears will supply lower sounds (woofer) Joining them together will give better sound usually, when only using 2 speakers, on a 4 speaker stereo. You may want to test with them joined and not, to see what sound you like better.
OK, HERE IS WHAT I SHOW. DID U KNOW THEY MAKE AN ADAPTER HARNESS THAT ALLOWS YOU TO PLUG DIRECTLY TO FACTORY HARNESS? NO CUTTING WIRES. THESE ARE AVIL FROM ANY LARGE RETAIL STORE LIKE BEST BUY. PLEASE RATE MY HELP, THANKS!

Id call you local stereo shop. I changed the head unit out in my old acura legend and had the same problem. You need to buy a special harness for the bose. Each speaker had its own amp, so i just rip it off and wired the speaker direct and trashed the amps. Now this was an older car and speakers were almost shot so no biggie. I would not recommend you doing that on and 04. Just call your local stereo shop and they should hook you up.
Does this only happen when you turn the stereo on? If so, it's perfectly normal. It happens when the amplifier in your stereo powers up. It's an older car with "unshielded" wiring that isn't going to be grounded properly. Oh, and to answer your question, yes, the plus (+) and minus (-) are for positive (+) and negative (-) terminals. Make sure that red is on positive and black is on negative. Reversing the polarity (installing the wires backwards) normally won't make the system stop working but it can damage your new speakers.
You also should make sure that you've connected the stereo ground. It will probably be screwed onto the back of the stereo and if there isn't a provided green wire in the bundle coming from the car than you'll just need to find a place to attach it to the car's metal chassis.
