DEH-14 harnes color info needed

It may be the most basic of newbie questions on here but I must ask....what colors go to what? Issue, no factory harness (due to moron chopping before we owned it) and have an old deh-14 that the wife wants in her truck. So, I have done many an install WITH the quick connects connectors, but never a fresh wiring install. I have a two part question. Part one what do the colors stand for on a scematic? Part two where is the best place to feed the power and ground and others into on a fresh wire install? Red yellow black (this I know is ground) blue w/white stripe and I would asume the next set are speakers gray gray w/black stripe Teal Teal w/black stripe purple pruple w/black stripe white white w/black stripe Thank you all.

No, wires are cut way back and the org harness had a factory amp in the truck which made for that much more crap. So, I jus said frig it and was gonna do it up myself. Thanks for the help.
