Hi I work as IT at Santa Monica schools , I'm having an issue with one of the IN24 proj. it showing wrong colors, green is yellow red is violet etc the lamp has 286 hrs used any sugestion?

Resistor color code is as follows:

Black-0/.0
Brown-1/0
Red-2/00
Orange-3/000
Yellow-4/0000
Green-5/00000
Blue-6/000000
Violet-7/0000000
Grey-8/00000000
White-9/000000000

The first and second color corresponds to the numbers .0-9
The 3rd color corresponds to the zero(s).

So, 512 would be: Green/Brown/Red (5100 ohms)
and 514 would be: Green/Brown/Yellow (510000 Ohms).

Red 12v permanent live.
Yellow 12v switched live.
Black ground earth.
blue/white amp or power antenna
yellow/black mute
speakers
white front left (-)
white/Black front left (+)
Grey front right (-)
Grey/Black front right (+)
Green rear left (-)
Green/Black rear left (+)

Your ground wire is going to be black. Your normal wire colors are violet and violet/black, green and green/black, white and white/black, last but not least you have grey and grey/black. Those are your speaker wires. Solid blue is usually to power your antenna, and blue/white is for your amp turn on lead. Those two wires are approximately .5mV of power, and you can actually use either one to turn an amp on. Speakers: normally your solid color is positive, while the black stripe is your negative. As for which one goes to which speaker, left front is white, right front is gray, left rear is green, and right rear is violet. Hope this helps.

You have placed them in the wrong order.

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 ?
