been searching round looking for a diagram on howto wire this so it runs constant but end up finding dead sites anyone done it befor?...

ST205 units run fulltime via defult unless your not running the stock ecu then you may have some issues, best to get an aftermarket pump controller. Bling and practical.

Why do you want to run it all the time?? It will just reduce the life of the pump
It will depend on how the pump is setup from factory. Some factory systems have the pump running at low speed continuously, switching to high speed at certain positions of the throttle and engine airflow. If you have the pump running all the time it must be capable of continuous operation. you could wire it so the pump only comes on when on its on boost, or have it switched via a temperature switch

When I wire my pump up I will have a switch which will switch between:

*Consitantly on
*Switched via throttle position or a temp switch
*And off (maybe)

its runing the stock ecu but the auto sparky who wired it in has cut the grey/green and grey/blue wires :/ to the ecu so im not sure what the thing is doing.... also has engine light on code 13/14

Decide on your control scheme first...
Then consider Davies Craig stuff, EWP or EBP, for a pump...

Or piss it all off , save 25 KG of weight over the front , and install a much more practical Frontmount - no worrys about pumps dying , or water leaking - just simple hoses pipes and airflow

for a lot of applications w2a>a2a
its been covered on here before

having a system when its off and switchs on with boost is a bad idea.
you want constant flow to eliminiate heat sink.
my aw11 was wired up to be on constantly with 2 legacy pumps.

Autospeed (www.autospeed.com.au) just did a couple or articles on an intercooler water spray unit... but thinking about it now the logic and control could be applied to w2a pumping as well...
The basic idea is roughly the same, and the function quite similar... There would be a few changes needed...
Might be worth a look at...
I'll think about it...
