UPdate-

Changed Blue-to-blue connection to current --Blue/white-to-Blue

Powers up sometimes* when the pink-to-pink connection touches yellow-yellow.

This only happens sometimes seems as if the unit has to reset after a period of time and will again regain power but does not consistently stay powered on.


Same results as Blue to Blue conn. and seems no matter what pattern the pink and yellow are in it will gain power periodically but not regain power after disconnect.

The second option is for Continuous power supply, then the red wire goes to yellow and the yellow goes to the red.
The third option is for cars without ACC position, then both the red and yellow from the headunit goes to the yellow that comes from the car.

Only thing is i dont remember wich one worked on my ZJ but one did nothing and one of them freaked out the ac panel.

Attempted all 3 options, I have an accessory switch, but only works when connecting both yellow to both red and still then, not always will it work :/

There may be a problem with the "plug and play" jumper. Maybe the wires aren't quite right. This is what you should have coming out of the unit itself. Red, ignition. Yellow, battery. Black, ground. Solid blue is only for power antenna. Blue white is power for the amp. Ignore the colors on the jumper. Connect the Red/white stripe wire from the dash to the solid red wire from the HU. Connect the pink wire from the dash to the yellow wire from the HU. Disconnect all other wires. Then one by one connect the speakers.
