Does anyone have details of the wiring for the STI7 Automatic I/C water spray? - Mine has stopped working.

I have checked all fuses, and they seem fine. The manual spray works fine, so it must be the triggering that is at fault.

The components of the system are:

- The ECU (I assume) - but which pin?
- The Auto on/off switch (lights up, so seems ok)
- Relay (not clicking any more)
- Pump (works)
- Other inputs (e.g. Throttle, boost) or is that via the ECU?

I just need to know how they relate and the pinouts so that I can check for faults... It used to trip over 4000 rpm on WOT - which could have been based on max boost level?

Any info on the wiring, ideas as to why it don't work and information on the sequence that triggers the auto spray would be helpful...

Thanks

I only thought it only worked with the manual switch any way!

That's on a UK car. His must be a JDM spec one.

oo I see.

Could a Uk spec STi be upgraded?

Yes, IIRC, MRT or somebody do a kit based on an intake temp sender cutting the I/C spray in automatically.

MRT had one on their webpage but it's either gone or it's so well hidden in an obscure menu that I can't find it.....
