Last time I tried I couldn't get the cable through the damn bulkhead, maybe I should just take it straight to the power block. I got a powerleads power cable around with an inline fuse, guess that would do the job connected to the #75 bolt in the link?

I used a PC3-11 adapter by auto leads on my standard Sat Nav H/U it provides four RCA outputs and an amp 'remote' lead (+12V when HU is switched on). It plugs into the yellow slot alongside the multi changer input in the back of the stereo. Got mine on ebay.
