The guy at repco is ill informed. The camira has a range of injection systems these include l_jet style which use a flap air flow meter. It has 1 coolant sensor and a time switch to the ecu when the engine is cold. You don't want this setup and it would be for early camira's say before JD camira( this is what the repco guy was looking at). The JD camira uses throttle body injection different to above you can see when you look at it, it has a carby like setup on the manifold. The JD setup most likely has the sensors you need. But to be on the safe side go for the JE camira sensors because these are the ones that will go with the Haltech system ( the map sensor does any way and I am positive the other sensor will) the air temp sensor will be in the manifold, the water temp sensor is on the back of the motor on the drivers side near the end of the manifold. Pick a part will sell them cheap say $10 or so for both. The same sensors can also be found on VN,VP,VS. The guy behind the counter at repco doesn't realise the air temp sensor fit in the air flow meter of the system he was talking about. $100 from haltech, there dreaming
