If you have the TCU (BT Module with Assist), it automatically goes into pairing mode for 30 seconds after the key is turned to ignition 2. Your phone will discover it and you have to enter the passcode that is found on top of the module. However if you have an ULF, you need a pairing button, or you can make one by connecting pin 17 i believe and the ground in the connector located inside the center console. I made one using a button from radio shack. Once you make the button, hold the button down for one second, turn the ignition on to position 2, keep holding the button for another 2 seconds and the ULF will go into pairing mode. Hope this helps
