Brake light wiring diagram?

So I’m wiring up my new topper today, and as I took the brake light off I realized there were three wires running to the brake light bulb itself. I assume the black/white one is ground, but there is also a solid green wire, and a green/white wire. I’m guessing one of these is for the running light and the other is for the brake light, but which is which? Hopefully some of you guys have experience with this. I’ll include the picture for clarification.

if there is already a thread containing the wiring diagram w/ color please tell me, also I don’t have access to avoltmeter right now so I can’t just test it the easy way. Thanks in advance

 

Solid Green "should" be your Tail/Parking...follow the wires down to the main connector and see which position they occupy.

 

Thanks, but I don’t exactly have real wires. I think I’m still going to trust you and go with the one in the 4 position.

it looks teal in the picture, but I’m splicing into the green/white one

 

The pic I sent is looking INTO the connector...

 

Well, I spliced into the green/white one and it works! I guess it worked out!

 

I put together a write-up together for this one on GFC Forum.

How to tap and wire the brake lights, reverse lights and turn signal lights.
