Stereo wiring help needed - Mk3 16v

[keith222]

I'm trying to work out the car stereo wiring.
I've read all the posts & haynes manual wiring diagram, but am still not sure.
I have a MK3 1996 golf gti 16v.

The speaker wires go into a brown 8pin block, & look OK & original.
Antenna looks original & obvious.

I have 5 other wires.

According to Haynes:
red/white = power
brown/red = ignition power (switched)
brown = earth

I need to identify these two:
blue/white = illumination???
blue/grey = automatic ariel/antenna extension???

Does the Benson manual shed any light on this?

The blue/grey wire is the live feed for the dash illumination

The blue/white wire should be the one for the amplifier in your beesting roof aerial.

many thanks, that makes sense.

I have re-examined the wiring diagrams & the blue/grey links up with other dash illumination devices.
I will put a multimeter on it, to see if there is any power.

The wiring diag, indicates there should be a black wire for the power feed to the bee-sting aerial, which I believe is a powered aerial. However, there is only 1 black wire in the radio loom, & that is wired into the brown 8 pin speaker block.
So if the blue/white is the power for the aerial, that would solve another issue.

I believe I need an adapter for the aerial (see link)

which needs a power wire.

As well as a VW to std aerial adapter

Another question:

Is the brown 8pin speaker block (the original VW one), the same pin configuration as an ISO speaker block?

Just compared a std ISO speaker block, with a VW conversion adapter for speakers.
The cables go to the same pins.
