But that ground connection is *not* sufficient to directly drive a high pressure solenoid. You must use a relay and, preferably, a master arm switch between the ECU and the solenoids being driven if you're using large solenoids. Trying to drive the solenoid(s) directly from the ECU **will** result in [[driver01|damage to the drivers]] inside the ECU. | But that ground connection is *not* sufficient to directly drive a high pressure solenoid.

- | ECMLink's output controls can be used for a variety of things. Our users have been far more clever in how they use this feature than we ever imagined. They have used it to control water injection, methanol, [[UseNitrousControlsForDejonToolBOVMod|blow off valve bypass]], and probably a few other things we're not even aware of. So this page is going to describe the general approach to using solenoid outputs of the ECU to drive a larger solenoid through a relay. The rest is going to be up to you and your particular situation. | + | ECMLink's output controls can be used for a variety of things.
