AV headunit

[RedGTI01]

Need to pick everyone's brains, just fitted my new AV headunit
(JVC KD AVX1; http://www.caraudiodirect.co.uk/product_info.php?products_id=4166)

now I need a little help with wiring the parking brake sensor to ensure that the monitor functions all the time, I've seen from a previous post that it needs to be earth linked but can anybody point me in the right direction for which cables to wire it to?

Thanks, Scott

any wire that is earthd... usually a black one from the headunit.
