Hello friends,
I am going to install a new diffuser that has a break light and I am trying to find the break light wire in the connector shown in the image. I already asked this question but I had no replies so I disconnected the connector and started trying each wire and found that: See image
Wire 1. Ground (Brown)
Wire 2. Brake (Gray/Blue)
Wire 3. Brake (Blue/Black)
Wire 4. Lights (Yellow/Pink)
Wire 5. Reverse (Blue/Black)
Wire 6. Indicator (Blue/Brown)
So I'm confused since I found 2 break light wires. Any help on this, why there are 2 break light wires?

Thanks in advance

I don’t know why there is 2 brake light wires.
To answer your question,
Remove one of the brake light wires and have someone step on the brakes while you check for voltage.
If there is voltage when the brakes are applied, then just run that wire and a ground wire to your diffuser light.

Hi serf27,
Thanks for your reply. I did that already, but I'm going to check it again.

Hello,
I tried again to check which is the break light wire and it gave me the same result. Wires 2 and 3 are brake lights wires.

Today I also checked the left side tail light and it gave me that wires 4 and 5 are the break light wires.
Wire 1. Indicator (Blue/green)
Wire 2. Reverse (Black/purple)
Wire 3. Lights (Yellow,thin black)
Wire 4. Brake (Yellow/thick black)
Wire 5. Brake (Yellow/gray)
Wire 6. Ground (Brown)
Sorry, image is not so clear.

So both left and right tail lights have 2 brake wires.
Any help is appreciated to find to which wire I'm going to connect the diffuser break light

Thanks in advance

One of the brake light cable is for the emergency braking light aka rear fog light. Is either that, or the fact that there are two brake bulbs.
