Can anybody tell me whether you can tell the difference between a pf01 and a pf09 Throttle Position Sensor just by looking at them???

Am I right in saying that the pf01 came in red and the pf09 came in black?
I know internally that they are the same apart from the voltage readings work in reverse.

I cant remember which one I have bought but I did have to reverse the TPS wires to run the car on a L8 when trying to get it running- does that mean it must be a pf09

I think I bought a pfo9 to run a L6 ecu with the cossie management on the series 2. I've since found out that I will require a pf01 to run a L6 ECU.

Anybody help please?
