well i got robbed back in july in addition to hu being taken the radio bezel was also ripped out along with harness. so im getting ready to get another hu, possibly the same one (pio deh-p4900ib). i was looking at the wires yesterday and none of the wires looked familiar to me. so my question is how would i go about running the hu off the batt? i know i can ground(black wire) to the - and yellow(batt) wire can be wired to + of battery. how do i wire the red(ignition) wire? somebody chime in and let me know what i need to do safely step by step. this is going in a 99 mustang if that matters.

wat i have done before is take of the steering column cover and find the ignition wire in i used a fork spade connecter with one of the forks cut of and wedged it into the back of the wirin harness for the ignition, or you could run it to the fuse box,

but if you still have all your wires where your radio goes, and just the harness is ripped off. you can just hard wire it into the pioneer radio harness, the only hard part is the tight spaces, if done it in a few cars where i wasnt able to find wire harness adapters. if you need to know wat each wire does, just look for your cars wire diagrams on this site: http://www.the12volt.com/

ok cool i'll look at that cuzz it doesn't have the standard colors for the wiring(red yellow black)

Car companies don't use the same wiring colors that are standard in the aftermarket. Each automaker has their own way of color-coding things. Do a search online for your car and radio wiring and you should be able to find what you're looking for without having to resort to some type of ghetto rig.
