Your display panel needs replaced

I think this is the right table, but I don't know if it will display right. If not, go to http://www.installdr.com/InstallDocs/GM/PDF/460005.pdf

Hello chrisuftring,

Here's a link to the wiring color code for the '95 Chevy Beretta.

You'll need to match the function of each wire from your head unit and the color code for that would be in your manual. Most aftermarket units are somewhat standard as far as power, accessory, ground, and speaker connections are concerned. But the wiring colors may be different for such leads as remote, power antenna, illumination, dimmer, and muting.

An Alpine head unit has the following wiring colors:
Blue - Power Antenna
Blue/White - Remote
Pink/Black - Audio Interrupt (muting)
Orange - Illumination
Red- Switched 12V+
Yellow - Constant 12V+
Black - Ground
Gray - RF Speaker (+)
Gray/Black - RF Speaker (-)
White - LF Speaker (+)
White/Black LF Speaker (-)
Violet - RR Speaker (+)
Violet/Black RR Speaker (-)
Green - LR Speaker (+)
Green/Black - LR Speaker (-)

With this head unit, you would wire Yellow to Orange, Red to Yellow, Black to Black, Orange to Gray, Blue to Pink, Gray to Light Green, Gray/Black to Dark Green, White to Tan, White/Black to Gray, Violet to Dark Blue, Violet/Black to Light Blue, Green to Brown, and Green/Black to Yellow.

Note that there are 2 "yellow" wires in your vehicle color code. You'll have to test them to determine which one is the accessory wire and which one goes to the left rear speaker. Using a 12V "test light" is the simplest. Connect one side of the light to ground. With the ignition ON probe the yellow wires. One of them should light the tester, the other one won't. Verify that the light goes out when the ignition is OFF and your have separated the redundant "yellows". The one that lit the tester is your 12V+ switched wire and the other one goes to the left rear speaker.

Hope this helps.

Hello uze7, Here is the wiring match up for a 2009 Subaru Forester using the Metra 70-7552 wiring harness: NOTE: The actual harness will be listed as a Nissan harness, but has been used by Subaru since 2007. Also, I'm assuming that your Sony deck uses the standard color code. If not, you should have a manual that lists the function along with the colors. Match the wiring by function, not by color (although the colors may be the same). 2009 Subaru Forester Radio Wiring Color Code: Battery BLUE/RED (+) RADIO HARNESS Accessory YELLOW/RED (+) RADIO HARNESS Ground BLACK (-) RADIO HARNESS Illumination VIOLET (+) RADIO HARNESS Dimmer BLACK/WHITE (-) RADIO HARNESS Power Antenna YELLOW/BLACK (+) RADIO HARNESS LF Speaker (+) BROWN LF Speaker (-) BROWN/WHITE RF Speaker (+) BLUE/WHITE RF Speaker (-) BLUE/YELLOW LR Speaker (+) WHITE/BLACK LR Speaker (-) RED/YELLOW RR Speaker (+) GRAY RR Speaker (-) GRAY/RED Metra Harness: Yellow ? 12V Constant Red ? 12V Accessory Black - Ground Orange ?
