i well look and try to find factrory colors for you... chiltons/hayes m,anuals usualy list this if you wish to purchase one. i find mine invaluble. you can run 12volt constant from batter juts put an inline fuse 10-15 amp should work. the ignition wire can be ran from fuse box. but dont ground from casing around the deck this can cuase problems ground strieght to the body pan of the vehicle.

Chill friend... we'll get you there!
If you have a 12 volt test light or Voltmeter, this is easy to track down which wires go where. Here's a summary of what to look for:
If you are tapping power from any other fused circuit, (Ie: dash lights, brakes etc..) you do run the risk of blowing a 10A., fuse if the circuit is already connected to some other devices. (overlaoding the circuit)
Your basic wiring scheme for this HU is:
1. Red = +12 volts wired to ACC/IGN circuit or even a cigarette lighter
2. Yellow = constant +12 volts for station memory, clock
3. Black = Ground, connected to bare metal ground such as floor pan or metal dash supports.
4. Blue = there may be 2 blue wires for +12 volt output to remote amp and/or power antenna. (your manual will tell you which is for what functions)
5. Speaker wiring in pairs, 4 different colors used
NOTE: Factory HU's use a harness ground which is not always best for Aftermarket HU's.
Your factory HU colors may not match up with Aftermarket HU wiring harness colors. A 12 volt test light or Voltmeter will help you probe the wiring harness for proper wiring connections. Since your factory harness wiring was cut, you'll have to probe for correct wires or as Chronos mentioned, get a service manual for your car and do you wiring based on that info.
BTW, if you plan to keep this car for a few years, having a service manual will save you hundreds of $$$'s in repairs and diagnostics. Most good auto parts stores have them as migh WalMart.

I might have the factory wire colors in a book at home. I will try to remember to check when I get off work tonight, if not remind me.

It sounds like your dimmer wire (from HU) may be connected to the wrong wire in dash. This will blow fuses and may cause other problems as noted. Let's see what ttocs has in wiring codes for your vehicle.

I agree with everything swez says, except for---"1. Red = +12 volts wired to ACC/IGN circuit or even a cigarette lighter" Most cigerette lighters are a +12 constant, not switched.
I will give you what my books tell me... They are right probably 75% of the time, maybe less. It should give you a good start if it is not correct. A little testing and we can get it...
drivers front+white/blue
-black/blue
pass front + white/red
- black/red
drivers rear + yellow/blue
- gray/red
+12 constant is white
+12v switched should be black/white
To test the speakers take a AA battery and touch one wire to the posative side, one to the negative side. The speaker that corresponds to the two wires will make a light pop. If you don't leave it on more then a sec or two, the speaker will not be damaged. Definitly test all wires with a voltmeter first with the key off, on, and then the lights on....
