Firstly, this pic shows the smoker unit fitted inside the funnel, you can hopefully see the brass ring round the top of it, with the pin in the middle....

These are the 2 wires from the unit (doesn't matter which way you connect them to a battery), the hole is so big as I was originally planning on fitting the smoker into the hull and have the superstructure fit over, however I decided it'd be better to fit it in the funnel....

Here you see the needle used to fill the unit with the oil, doesn't need putting in a certain place, just anywhere around in the tube surrounding the central 'needle' in the unit, I think the instructions say to put 0.8ml at the most in, and that should last approx. 20 minutes

And this is how much smoke it makes...
