thats easy, wire up a relay and have the relay ground controlled by the ems.for example you can wire it up like this
ground the pump to chassis ground.run the b+ out of the relay to the pump.on the coil side of the relay run your 12v in and run the ground to low side driver #ls3 in the ems (just as an example)
next you go into the ems and click options>configure outputs
on the drop down menu selct ls5 and check basic activation.
if you want the w/i to come on at say 12 psi you want the basic activation to look something like this
coolant temp/at least 160*
load/at least 12 psi
rpm at least 3000
tps at least 80%
road speed at least 20 mph
that will make it work but i would suggest putting a switch on it as well for activation.to do that you click switched ouput configuration and setup the switch parameters for however you wire it up
EDIT: WHEN YOU USE AEM LOW AND HIGH SIDE DRIVERS DO NOT USE LS OR HS 1-4. USE 5-8 EITHER HIGH OR LOW.THE REASON WHY IS WHEN YOU KEY ON THOSE DRIVERS WILL PULSE FOR A SECOND. YOU DO NOT WANT YOUR NITROUS OR METH SPRAYING WHEN YOU KEY IT ON!!
