I need help on how to connect the door trigger switch please. The instruction only says on pin 10 of the 14-pin connector, the gray wire is for the door trigger. And the diagram shows "Gray (door trigger + or -)" and the interior light and then the door switch. A momentary switch has 2 terminals and here only 1 wire is showing on the diagram. In addition, it says + or -. If anyone knows how it is supposed to be connected, please let me know.
Your help is greatly appreciated.
