I do appreciate the help, so you will have to excuse my ignorance, but if I may ask how is a schematic going to assist this query, surely adding a ground to any resistor circuit would have the same effect on that wire, all I would like to know please is what does the resistor do to that ground wire, how does it affect the ground switch/signal, its a resistance circuit so what does it create resistance on, surely a ground is a ground, now if it was a live wire we could figure its job out.
To draw a complete schematic, I would need to take the door module apart aswell, I know what I want to do works, so I could just install it & not worry about understanding why, but tbh thats the easy & copout way, I like to learn, so I would like to know/understand why it works & what a resistor does to a ground switch wire before it gets to the end means whether it be a transistor or another component.
Also completely off topic, where's the thanks icon, lol, as wanna thank people for there help.
