Yes, but sometimes you don't have an extra relay to use... so this method works just as well.
It's suggested to install a quenching diode across the coils 85&86. This will prevent your nps switch and ecu from being fried once the magnetic field collapses from removing the power souce to the relay.
Depending on how you wired 85&86, cathode (ring side) of the diode is wired to the 12 volt source, anode side (non ring side) is wired to the other side.
So, if Pin86 receives +12volts, then the cathode side is wired to Pin 86. if Pin85 receives -12volts, then the anode side is wired to Pin 85.
Either way, you still need a diode!

IT CAN DRIVE A RELAY! MINE DOES. READ RELAYS FOR DUMMIES ON SCOOBYMODS.COM AND IT HAS A POST HOW TO DO THIS WITHA RELAY AND NOT USING THE HOOD PIN SWITCH INPUT, BUT USING THE NEUTRAL SAFETY SWITCH INPUT OF THE ALARM AND THE EBRAKE. I HAVE DONE THIS ALREADY. But I aslo am a DEI installer.
