heres some update pics to show where i fitted unit



update (re: inverter)
well i got the inverter fitted in and did my first test of one of these things to see what sort of power it uses to biol a kettle of 240 volts, i was quite surprised didnt seem to use much, power was at 12.87v then when kettle was on it went to 11.67v, after a couple of minutes the kettle was bioled and volts went back up close to 12.8, when testing i didnt have engine ~(charging at 13/14 volts) running and the kettle was a 600 watt one, although according the the meter on the inverter that shows either volts or watts, the watts were 430watts to biol kettle and not 600watts as the kettle actually says it is on base.
yes very impressed with this gizmo
