I got this deck with a car that had the Alpine CDA-7940 in it with no wiring plug attached. So I was thinking I could build my own if I knew what each connector pin served. (i.e. battery, ignition, remote, illumination, and speaker (+) and (-) leads. I imagine any slightly newer CDA deck may have a very similar pinout for the main harness. Can anyone email me a resource with the exact info? Or does anyone know? I would appreciate it a lot!
Facing the back of the 7940 the top left corner is pin 16 the top right corner is pin 9. The bottom left is pin 8 and the bottom right is pin 1. Only a few of the 16 pins are used due to this unit only having pre-outs, no internal amplifier on this unit. Pin 1 red (ignition), Pin 2 pink/black (interrupt), Pin 3 orange (Illumination), Pin 8 black (ground), Pin 9 blue (power antenna), Pin 10 blue/white (remote turn on), Pin 16 yellow (battery).

Hi I believe you have an Australia model? Alpine's use what's know as an interrupt wire to hook into vehicles/phones to interrupt the audio of the deck when their is a signal sent to it. On the Alpine harness you need to search for the Pink/black striped wire which is the audio interrupt wire. Make sure that wire is insulated and not grounding out against anything or hooked up incorrectly.
Check for blown fuses behind the deck and under the hood, sometimes by the battery, you may get lucky but you could have smoked the unit, and would not know anything unless you send it in to get fixed. Replacing the unit could be the answer Alpine CDA-9883 CD Player
no - the harness is $17 or less.
Even Metra makes one (pictired above)
In my shop I charge $17 for the metra plug.
Metra part# AL16-0001 or al2x8-0001 CLICK HERE for an eBay auction for an original ALPINE plug. $30 CLICK HERE for an eBay auction for a $2 (shipped) one.

you go to a stereo shop..(walmart autozone etc should also do) buy a mounting kit and a wire harness adapter. The wire colors on the adapter match the wire colors of most aftermarket decks. MAtch the wire colors and connect...make sure to tape wires well as if they touch you rick damage to your deck..
install the mount kit plug in your cd player and slide it in and you are good to go..
Some 4-Runners have a factory system that uses a separate amplifier to power the rear speakers. In this case you need to activate the amplifier using the blue/white remote output from your Alpine deck. It sounds like the wire that activates the amplifier is currently attached to the deck's blue "power antenna" output, so that the amplifier is only on when the tuner is selected.
Disconnect whatever is attached to the blue wire behind the deck, and attach it to the blue/white wire instead. That should solve the problem.
