Head Unit Illumination Issues!! End of tether PLEASE help!

No worries, good luck and be careful with the sparky bits!!

Okay - before I start - do I actually need a switched ignition live?  The old headunit only had a permanent live, and earth and one other which I didn't identify?

Also, if I do need one, there ain't one there - so where can I take one from??!

From what I've read too - the blue and grey wire appears to be the dimmer wire?  Is this right?

Thanks!

Most, if not all, modern h/units need 2 lives, a permanent live and a switched/ignition live, because Mk2 golfs/jettas were never wired with an ignition live you need to eithr run one from the switched part of the fuse box or splice into the ignition switch (position 2).
The additional loom you bought provided a live to the switched part of the circuit by shorting the permanent live to it ie always on.This might be why the illumination wasn't turning off because the stereo wasn't actually switching off.
Either cut the yellow wire on the loom you bought and attach this to a switched live or as previously said remove the front panel every time you leave the car

A HUGE thanks to those that posted!

After all, I just cut the live feed that was going to the switched feed and voila.  It works.  I've still yet to splice the heater switched live to the head unit in the right place, but it works!!!

Thanks once again guys.  You ROCK!!!

Si.

Just gotta wire up some speakers now!!!!
