So which wire do I use from the loom to make stereo dim?

[cpt kernow]

My factory no-name headunit has two wires to dim the display when the lights are on.

One is purple, the other black with dots. My new stereo only has one cable for dimming.

Probing around shows the existing wires have +12v when lights on. I assume the purple one is +ve and the black gnd?

But when wiring the dim cable to the purple one, nothing happens to the display. Is this a headunit thing or did I use the wrong wires?

The factory service manual only shows purple and black wires for dimming but not much else.

Cheers

come on, I can't imagine that I've exhausted the collective knowledge of the forum?

My suggestion would be to go to Repco / Supercheap and look at the packets of the loom adaptors they have, make sure you find a subaru one. Find on the back which colour wire they say is the illumination one. Make note of which pin it is in the plug, then go home and match the same pin. That shoudl be your wire.

This is assuming of course, that the loom adaptor HAS an illumination wire haha!

[cpt kernow]

true.

Will try in the morro

So the ones coming out the loom to feed factory stereos/AC/Dash are maybe not the only ones.?

There is only one loom that connects to your stereo.

No, the loom provides a plug for the back of the stereo, but provides two loose wires that dim the headunit when you turn the lights on. Taps are taken off this purple and black combo at each place you want things dimmed. The dash, AC, and clock etc. I find it funny there doesn't seem to be a feed from the headunit plug.
