Generally, the 4 wire plug is for power only.
The 12 wire is for speakers only.
Most often, plugging in the 4 wire may get your radio to "light up", but you would have no sound.
By the same token, the 12 wires plug only power the speakers, so hooking it up will not power the radio to work.
God bless your efforts.

you should never cut the wires on your factory harness... metra and other companys have harnesses that fit your car and would provide you with a correct wire color code you need to hook up a aftermarket stereo keep that in mind but i will post the wire diagram u are looking for

Dave,
You will need to go buy a wiring harness adapter from your local Walmart (usually cheapest there) or Local Electronics place (ie Best Buy). The wire harness that goes out from the radio goes into the Adapter and the adapter plugs into the car harnesses. Also these Adapters come with the wiring diagrams for your vehicle. They typically run 10 - 15 bucks depending on where you get them. Thanks for using FixYa!
Sincerely,
JC

I'm assuming you're just going to splice into the tail light wiring so that's what these wire colors are:
at the tail lamp 3 way connector:
black and yellow = park lamp
dark green and brown = left turn signal
there should be another connector with violet and black wire for reverse lights.
the stop lights are turned on through the turn signal circuits.

Theres a standard amongst most stereos, so if these colors apply, then you will be right,
Red is Ignition power
orange is direct power
Black is earth
blue is for phone
White is for electric arial
then there will be four coloured wires with matching color trace wires, these are the speaker wires.
Hope this gets you going, good luck.
