Yep planned all along on fitting it myself and finished the job yesterday. Test drive when the rain stops.
Invisibrake and voltage reducer are under the drivers seat. Invisibrake is bolted to a shelf I made and the converter stuck to the carpet with velcro. There is a warning light on the M/H dash when the brakes on the toad are applied and has an audible alarm if the brakes stay on for more than 20 seconds. I used the 'service brake' wire in a 7 core trailer wire for this connection rather than run a separate wire between Wilbor and the Suzy. The invisibrake is great. It is air operated and has a vacum pump connected to the Suzy's toad brake system. It operates off the brake light from the M/H and is fully adjustable. It is powered off the Susy's battery and charges the battery while towing via the tail light circuit (you must drive with the M/H tail lights on)
Roadmaster instructions were very easy to follow with good illustrations.
I did have some reservations about the wiring harness but I bought a Suzuki repair manual with wiring diagrams on a CD and found everything I needed. The wiring went very smoothly
I had to get a 10" HI/LOW hitch because Wilbor's tow bar is 72cm off the ground

The jury is still out on any requirement for certification in Qld
