I bought a new garage door opener (Universal Transmitter) and installed it in my 2003 Xi. Doesn't work! No lights or any indication it's getting power. Used a digital voltmeter to check the connector and find nothing. No power between any of the terminals on the 3 wire connector. The fuse diagram says fuse 26, a 5 amp fuse that powers the circuit. The fuse is good. So, do I have the right connector? Are there any other connectors I'm not seeing? Does anyone have the wiring diagram for thus particular wire? The Bentley manual I bought doesn't show this circuit.
