Ok Here We Go , I changed the connector on mine to suit my needs . Hopefully you can see the picture well . I see your pigtail changes wire colors ,so I am going to talk about wires colors before the pigtail . Both Green can go to chassis ground or battery negative . Black Wire Needs to go to a Keyed or switched positive power source I.E. battery power, And also. you may be able see in the picture tagged for the power side of the led /CEL . Red is only used as the negative side of the led /CEL (malfunction indicator light ) I broke the CEL that was sent to me >so just used another led , I am not sure it was necessary . But in my thoughts since the red wire goes straight back to the controller , grounding the CEL flash . I added a resister of few hundred ohms . LEDs do not need much power to work and I think keeping amp loads to the controller low reduce heat in the controller. small resister hidden in the connector .
