First off to install aftermarket head units is pretty simple. If you are one of those that when you buy something and just install them by yourself and then when you see all those wires and dont know what to do...then this is for you. To install a head unit you dont need to buy new wires (ie wiring harness). First off you will need a circuit tester, scissors, electrical tape or crimp caps, screwdriver, and a double A battery. Start by taking out your stock stereo. Dont cut any cables off just yet(this is IMPORTANT b'cuz if you do it will be harder to find the right wires). Use your circuit tester and look for the constant 12 volts. Make sure your car is not on though. Once you found it cut it out, but make sure you cut only the constant, then from your head unit's wires get the yellow wire and twist the constant and yellow(battery)wires together and tape it or use a crimp cap, make sure they are properly connected to each other correctly. Next turn your car on the ACC position and with your C.T(Curcuit Tester)look for the Ignition wire when you have located this wire turn your car off and cut the wire off and tape it to your headunit's red wire. once you have done this connect the antenna to your headunit and turn your car to the ACC position and place the ground cable (black) to a good ground source (usually to test it place the ground cable to a metal part {chassis} of your car) make sure it turns on. Good job if it does. Turn you car off. Next with the AA battery you are going to search for the speakers. Cut the remaining wires left (but by pairs) and place wires to each end of the battery. If you hear a noise coming out of the speaker (like a bad transmission noise) then you found one speaker and connect and tape it to the proper wires from your head unit. Do this until you find all the speaker wires. Once you finish retest again and if you need a ground cable (black) connect it to a remaining wire. Retest again and if it works then your are finished. But remember when testing to make sure your head unit turns on you need to connect the antenna cable. then just palce your headunit in the car and enjoy.

As for the power issue, how do you have the wiring set up? Did you buy an aftermarket harness from a store that clips to the old harness? Or did you just sever the factory clip off and make your own?
