What are the colors of the wires for...Battery constant 12v...12v hot only when ignition is switched on.....ground.....and front & rear speakers + and -

Get yourself a digital multimeter. Find the +12V constant, 12V remote, and ground. Connect them to the new head unit. For speaker wire get yourself a 9V toy battery and listen to poping noise. If you have a factory amp you need to power up the factory amp. Use the wiring diagram below to serve as a guide. Test your wire first before connecting them.

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 ?

with the ignition in the "off" position get a test light and touch one wire at a time while cycling the ignition switch to the "on" position, When you see that the test light goes off when the ignition switch is in the off position then you found the hot wire, make sure you dont hook it up to the "alway hot " wire or you might drain the battery hope this helps.
