Generation IV External Engine - LS2/LS3 Throttle Body to LS1 adapter?

I've noticed a few vendors selling LS2->LS1 TPS adapter harnesses.

I need one for a car in Australia (ls1 car being fitted with an ls3).

- i am not sure if the US adapters will work with Holden cars.

Before i buy one (adapter) could someone tell me if the USA LS2/LS3 throttle bodies are branded Hitachi?

thanks!
