Puddle light install questions

[jeremyyn]

I recently bought a logo projector for my MKV GTI and supposed I could wire it to my interior lighting to turn on and off as I open and close my doors. But I've had the issue of constant power to fuses so I've had to use switches for my LED footwell lighting for example (They're LED strips) well my question is, I've seen the DIY by USP for the LED puddle light, but I want to know if the wires that they use to put into the module are positive and negative (ground or earth) wires. The video can be found here - https://www.youtube.com/watch?v=khAceNYE6D8 And the wiring part I'm wondering about is at 3:30.

Any help will be highly appreciated. I just don't want to use the switch anymore and wish it could just turn on on it's own. Here's a pic of how it looks anyways.

Yes, the red wire is +12V DC and the brown wire is ground/earth.
The circuit that is added is monitored and will fault for insufficient load,
but I assume their device deals with that.

So do you mean I can't put regular positive and ground wires into that module in place of the wires they use?

Would you know of any other way to wire the logo projectors?

I am not following. :iono:
The two wires from the projector are added to the existing connector on the door control module.
The two projector wires are 12V DC and ground / earth.
The module provides the switched 12V DC source and ground / earth connection.
I am not certain, but I suspect those terminals are provided to drive
the safety light on the inside of the door that we do not get in the US
(we get a passive reflector instead).
So the 12V DC source will be switched accordingly.
Also, the module not only provides power, but also monitors the power consumed.
It is set to monitor for a typical 5W incandescent load,
although it has fairly wide range of acceptance both above and below that.
Still, some LEDs are so efficient they do not draw enough power
and will cause the monitor to extinguish the 12V output after it lights up for a few seconds.
But I suspect the supplier knows this and has provided sufficient load to keep the controller happy.
The monitoring is only of significance if you are trying to power something else
or if you are trying to meter the 12V output.

So what you're saying is that it MIGHT work or it MIGHT not? Do you recommend I try plugging it into the module?
