12V power for trailer hitch

I have just mounted an after market trailer hitch on my 2006 307 HDI (90hp)
stationcar.

Theres a cable for a little controlbox that needs 12V. From where do I pull
this?

Pulling a cable straight from the battery seems impossible, but shouldn't
there be power to be pulled from somewhere inside the car? Afterall, what if
you wanted to mount a cd-changer, amplifier or something like that back in
the rear?

Any ideas appreciated.

My old 206 has a factory fitted CD changer connector already in the
boot. I'd be suprised if a year old car didn't. Have another look.

 

I had this problem last week on a 207. You have to be very careful
where you take a live feed from on a fully multiplex car like the 307,
207 and later 206. I had to run a wire up the inside of the car under
the sill trims to the ignition lock and solder into the main live wire
to it. Also needed an accessory feed which I took off the cigarette
lighter. On the 307 I could've used the 12v accessory unit in the boot
if fitted. Otherwise the one in the centre console.

 

There is what looks like a 12v accessory in the rear left, but theres no
power in it.
I have confirmed that in the fuse panel, the "12v front/rear" is fitted.

Any ideas as how to get power through here?

It might only be powered with the ignition on.

 

Tried that. No power. :-(

I would speak to your PUG dealer. I agree with what Nigel said. You
do need to be very careful where you take power from, especially if it
will be of high current.
