yea the unit is split into 3 curcuits, the red wire is power to the unit itself for your remote to work and boot release n so on, then the last 6 wires from the yellow/black to orange wire are 2 seperate cucuits an unlock curcuit and a lock curcuit that's why u have to put the yellow/black wire and the yellow together other wise only the unlock or lock side would work, oh Yea n i would advise u to put a fuse on the Y/B n Y wires if your taking the power from an unfused source just incase there was ever a problem it'll stop your car setting itself on fire
