Toyota Blade Master Cruise Control

[lilpopjim]

Hello guys and gals,

I recently purchased a Blade Master with the 3.5L V6. Unfortunately this one isn't the "g" version so it doesn't have the radar cruise.

I've gone the route of installing it manually, so I have the stalk and wiring for it however this particular model isn't prewired.

I've identified the pin on the steering column, which takes the signal from the control stalk and sends it out, however i'm struggling with the ECU side.

I have no idea what Pin number it is on the engine ECU which receives the cruise control signal.

After a lot of research and checking wiring diagrams for all the different engines for the Auris, I came to the conclusion that it was Pin No. 40, however that is occupied on my ECU, meaning it must be something completely different on my particular engine/ ecu set-up.

Does any one have any information, or the ECM wiring diagram from the ecu or anything at all that can help?

Anything is appreciated.
