Is that the 4th July? I will probably be going, but its not a definate. Mine is behind the clocks down the back and is around the area below the steering wheel, so its out of sight. No Idea why its on top of the dash.....
If you didn't live so far you could pop over (well you're only 40mins away) and i could take a look at it for you and compare it against mine. Me and N80Jamie are putting my car back to my EWG setup tonight from about 8 (weather depending).. But Yes, that little black box is the transformer thingy.
Its been known for the little transformer pack to blow, which IIRC cannot be changed. I wired my own in. Are they deffo connected tightly to the plugs at the midway point on the wires?? Are the wires further down attached properly to the relevant 12v Lighting Switch and is the dimmer pad still there?
