isolater/auxiliary cig lighter ?

I want to fit an isolater switch to a 55 plate diesel vauxhall astravan, we have fit homemade switches previously, usually grounding the diesel pump solenoid wire, but have been told this approach could screw up the electronics on this vehicle?
The cigarette lighter (12v power take off) is only live with the key in on the third position, all dash lights on. It would be handy to have another wired in at the rear next to the light cluster that can be used while the key is out the ignition. Does anybody know which wire I should be looking for and fuse rating I should use?
