So looking at this diagram from s2central.com
I want to use the +12/ground from the headlight washer pump to drive my pump for my water injection.
As far as I can see then the power to headlight washer pump is controlled by relay J39 and it seems to be interconnected to the wish/washer relay J31.
My water injection unit has a wire to start pump, so thinking of just using that to trigger relay J39 and then make a smaller adapter cable from the headlight washer pump to my water injection pump?
I'm reading this right?
