Question for those that have installed the trunk release using an OEM switch: the switch and pigtail I received has four wires coming from it (black, black/grey, blue, purple). Since mlsully said that it's a negative pulse switch, I'm assuming I'll be using the two black wires to complete the circuit (please correct me if I'm wrong). If that's the case, which of the remaining blue and purple wires would be used for illumination and what is the extra wire used for, if anything? My pigtail came from a Nissan Murano, if that matters.
