NEXUS R5 WIRING
Injection Outputs
All Injectors are to be wired directly to the ECU’s
corresponding cylinder output pins.
When an injection event occurs the ECU will
ground the output pin, opening the injector.
All injectors must be wired to a common +12V
supply from one of the High Current Outputs on
the NEXUS R5.
When not used for injection, pins can be used as
generic Digital Pulsed Outputs (DPO) capable of
switching 2A to ground.
Specs:
• Current controlled output
• 4A Peak, 2A Hold
• 0 to 55V voltage feedback
