Wasn't successful tracking down the relay, as I couldn't find continuity between either the cig lighter and any of the visible relays or the wire at the fuse box and any of the visible relays. In the end I just used the power from the unused gas heater supply (which wasn't an optioned on my car) to power the lighter and did away with the relay. Both earlier and later cars didn't have the relay, so I decided to do away with it. The lighter now seems to work, but during my investigation I have created another problem. My ignition light fuel gauge, temp gauge and rev counter are working in reverse. The ignition light won't light up until the engine is running and the revs are increased. The rev counter isn't showing true revs and the fuel gauge moves slightly when revved hard. I've gone back over what I've been doing today, but cant rectify it.
Anyone have any ideas?
