 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. ​ 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.
  
-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. ​ 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.

-First, let's get the ECU pins out of the way.  You can get a lot more information on the [[ECUWiringInformation|ECU wiring information]] page, including pin location and wire colors as well.  You'll want pin 57 on a 1G ECU and pin 3 on a 2G ECU.+First, let's get the ECU pins out of the way.  You can get a lot more information on the [[ECUWiringInformation|ECU wiring information]] page, including pin location and wire colors as well.

 +For the fuel pressure solenoid output, you'll want pin 57 (white wire) on a 1G ECU and pin 3 (blue with red stripe) on a 2G ECU.

 +For the EGR solenoid output, you'll want pin 53 (black with yellow stripe) on a 1G ECU and pin 6 (light green with red stripe) ​on a 2G ECU.
  
 You'll probably use a standard ISO (Bosch) automotive relay. ​ If so, here's the function diagram for this type of relay. You'll probably use a standard ISO (Bosch) automotive relay. ​ If so, here's the function diagram for this type of relay.
