Red for battery power
orange for ignition power

Need a wiring diagram for a DEH-X6600BT. IT'S GOING IN A 1993 CHEVY ASTRO VAN. I KNOW KNOW THE WIRES OF THE VAN. I NEED TO KNOW WHAT TO CONNECT TO ON THE RADIO. THAY ARE DIFFERENT COLORS.


I hope someone comes along who can help; in the meantime, you might try the following. Naturally the power wires will be 12V and usually red(+) and black(-), if they're not, you can examine the other colors, to determine if their are separate ground wires for each speaker. If it uses a remote, and you want to hook that up; I can't help. sorry. But, if the speakers have a common ground, there will only be 1 wire for each speaker, the other connects to the ground of the car. If there are two wires for each speaker, they will be 4 different colors, with a 2nd wire which has the same color for all 4 speakers, so each speaker has a colored wire, and a common colored wire. This will leave the power connections, unless you have other controllers (see above).

One you know which are the power wires, you can connect them to a spare 12 V battery, and then comes the fun part. While adjusting the radio for front back, left and right, using the colored and a common wire for each speaker, this will be the same as the ground wire for the power even if not the same color, you can connect it to ground for the test. Then connect the colored wire and common wire to a speaker, by adjusting the controls you can find out if that colored wire is for front or back, left or right. Then you'll have your color code.

Although prolonged use of only one speaker or only two could cause damage to the radio, short use to troubleshoot at low volume shouldn't be an issue. Just don't use it that way.for a long time!

I hope this helps. Let me know.by rating up my answer! :-)

What color wire


find the wire that has power when the key is in the run position and off when the key is off and piggyback that wire.. Normally the radio is wired into the accessories wire so that you can listen to the radio without having power run through the coil and burning it out. That wire will have power when running and when turned to the accessories position.

Trying to get the color codes for the speakers wires someone cut my radio wires and im trying to install new one.


Usually speaker wires have a solid color, and a stripe of another color on them. Sometimes it's a solid color, and rings going around the wire of another color.

The striped wire is the Positive. Then there will be a wire, that is the same color as the stripe. (On the striped wire) This is the Ground wire.
