All you need is "key on" power to the relay trigger & you can connect your overide switch between the "key on" power source (10 or 15 amp power w/ key on) & the relay, if your overide fan switch doesn't require "key on" power. If your overide fan switch does require the key to be in the on position, then jumper from that "key on" power source to the relay trigger. Then a low current ground for the trigger.

Then run 30 amp power from battery to the relay & a ground wire sized to ground 30 amps. Then run the 7.5 amp fused water pump power line to the relay. Sorry, I have no drawing, but, I think that Meiziere has a wiring diagram posted on their site. Their diagram will clear up where to connect to on the relay.

I used the fuel pump relay as my trigger. The PCM controls this relay. This way if you ever key on with out starting the car the water pump will not run.
