Hi, i have an octavia year 2005 and i am installing remote central locking too just a few questions: 1.when opening the door, there are 3 connectors and as i know the middle one is for the motors and it has 4 wires, 2 thick ones are power and the other 2 are the comand wires. am i correct? 2.central locking is negative type 2? 3. does it need an 180 ohm resistor for locking and opening, and if it is true, why there are 2 command lines? hope some1 can help Regards p.s. (sry for the bad english)
