Hi guys

Just found that my intercooler spray on my sti v2 is not working. Managed to suss out it isn't the pump by connecting the pump up to the wiring on the washer bottle and it worked fine. I checked that the switch on the dash is getting voltage and indeed it is, also checked the switch switched, which it did. This leads me to the wiring which is probably the cause. Now the question....who knows the wiring for this manual ic spray?

Please help!
