I'm trying to hook up an eManage and I'm a little confused about what to use as the Injector Ground (DOHC ZC on an Integra ECU). All of the Injector outputs go to the resistor box and a single yel/blk wire comes out of it and goes to the Main Relay. Would this work as a ground?

 

yes you're a little confused.

actually the yel/blk wire is 12Vdc from the main relay. it supplies the resistor box with 12V and then drops the voltage to your injectors. these wires are striped (red/blk or yel/blk).

solid colored (red,brown, blu, yel) are ground wires going back to the ecu.

hmmm.

Well, the eManage only has input/outputs for each injector and a single ground. I have to use the 4 wires going to the ECU for the signal wires, now I'm really confused as to what to use for a ground.

 

ur rele backwards...

the power comes in from that injector resistor box...

the wires that come from the injectors to the ecu are actually the ground...that's how ur injectors pulse, by the grounding of the injectors, not the sending of currnet to the injectors...


hope that cleared up some of your questions
