i've got the quadlock to iso loom going spare as i fitted a full set of controls today.
fit's the facelift (full canbus) and allows you to fit an aftermarket HU.

the switched live (red lead) attaches to any +12 ignition feed.
eg the cig lighter.
unfortunately there's no fakra converter as i had to keep it for my new one. but they're only about £5 on fleabay.

it also has the wiring for illumination and a speed-pulse lead for all those with active satnav headunits

£6 posted.
