Emergency Door Draining Battery

[MattBChillin]

This is the connection to a long gone back door emergency buzzer. I believe it is draining the battery. These are the wires, I tried different patterns but couldn’t get my meter to light. If I take the pink one with the arrow and ground it to the chassis, the backup lights come on and I can hear clicking in fuse box. None of the other wires do this, just that one!
Do I just tie the pinks together?

Do you have an amp clamp? Start at the battery and follow the current until you get to the source.

I have the same bus and seem to have made the mistake of disconnecting the wrong wires during this process so be careful.

Also, could you post a pic of your side fuse panel for reference to where those wires came from?

So I figured everything out. It’s all color and number coded. In mine everything went to the front of the bus where it shows the pic of bus and what lights are on. Some I left but most I removed. Label and build a diagram with everything. The fuse box has all info on wires and where they go. Little daunting but it starts to make sense once you start to see where they connect or travel. So far no issues but I did put in a battery discount so I don’t get stranded.
