Positive light wire
- Thread starter Mataltea

I think you will need to provide a bit more, clearer information, do you mean the positive wire on the light switch?
The image below is from a document for Golf Mk7, dated 2017, showing electrical diagrams.
It should be most likely the same for Leon 5F.
The rotary light switch is identified as EX1 and the diagram shows that there are two positive wires:
One on pin number 4, colored black-yellow, connected to fuse SC34, 15a.
The other is on pin number 8, colored red-white, connected to fuse SC8, 30a.
Please make sure all the other cable colors & pin positions shown here match to the cable colors & pin positions on your rotary light switch before doing anything, just to be sure that this diagram is valid also for Leon 5F.
You can find that by measuring the pins using a digital multimeter.
Pin number 6 (brown) looks like ground connection.
It should be one of the pins 1, 2, 3, 5, 9 or 10.
Just get two measurements for each pin: one when the position light is on and one when it is off.
I don't know what you are tring to do but don't connect to that wire as it will be Can-bus
Sorry for My bad English but i need The cable positive when the position light is on for install extra light.
Do not Connect anything to the Positive as it is Can-bus, if you dont understand google can-bus
No, as in two replies above, the feed to the light switch is NOT a full 12 volt supply. It is simply a switched feed to tell the canbus to turn the lights on. All switching done in the body control module.
If you connect direct to the feed to the light switch you run a very real risk of cooking the body control module, which is not a cheap thing to replace and recode.
As stated above, if you do not understand canbus wiring, do not connect anything, you will cause a LOT of damage
Show us a picture of where you are testing and show the fuse, and does it go off when you take the key out !
NO.......Please listen to what you have been told in previous posts. Just look at the thickness of the wire - that tells you it is not a feed cable - put a high current through it and it will burn out the wiring and/or the BCM. It is a CANBUS cable which only supplies the signal to switch inside the BCM, DO NOT CONNECT ANYTHING TO IT
I think he is talking about the fuse now as he has been sending me private messages
For example for connect The dashcam
On the cigarette socket have the fuse20a and cable black/Red is on key acc i can use this or the cable go to bcm?
You posted earlier that you want to install an extra light. Now you post you want to install dashcam. There is a HUGE power difference in those two items, so what would be safe for a dashcam would NOT be safe for a light. Make up your mind - what is it you are trying to install??? Connect to a canbus wire and you are into major problems. The power is far easier to take direct from the fusebox.
BUT __ With the greatest respect, the questions you are asking are proving that you do not understand what you are doing with the electrics on the car. Do something wrong and you will regret it - it will cost you a lot of money to rectify, if you don't cause a fire and lose the car completely.
Take the car to someone who knows what they are doing, for your own safety and the safety of the car --- PLEASE!!!!
