R32 antenna wiring?

[BOoStEr]

I spent this afternoon fitting a new headunit into my R32.

Just as I was tightening the last screw I thought about this black wire with a red trace I saw that was taped to the two antenna coaxes.

Does anyone know what this wire is for?

I did a search to find out but all I found was a thread with a deleted pic labelled "R32 Antenna box".

Is this an antenna amplifier?

Where is it and what does it look like?

Does this black and red wire power it?

Was there a wire on the back of the stock H/U that should have been connected to the power antenna output on the new H/U?

I haven't tried the radio yet because I haven't wired the amps.

Damn, I screwed the H/U in the hard way to make it difficult to steal.

it wasn't the convertor from the japanese frequency to australian? they are powered units!

No, it's just a black/red wire that runs with the antenna coaxes from the factory. It has a joiner where it comes out of the antenna wiring and then runs into the loom.

My Q is does it then run in the loom to the plugs for the H/U and need the power antenna output to be connected to it.
