Is there a special way to reinstall the robber boot?

[amron]

During my attempt to install the reversing camera, I routed a wire from the left reverse lamp to the tail gate. I had to go through the robber duct between the body and the door. when I tried to reinstall it back in its holes, the left side - door - went right into its place. the right side was a different story. it has an inner white plastic tube and the hole's diameter seems to be too small to be able to accept the rubber as well. what's frustrating is that I'm sure that it was inside. what I've done, in order to avoid water dripping in, I've applied sealant compound as a immediately measure, but it's not the solution. I'm looking forward for your advice, since i"m sure I'm not the first one to face this issue.

one more thing that is indirectly connected - I would like to know if there is a point at or near the dashboard that has +12V on it when the reverse is engaged. 

Thanx.

I removed that some time ago to check for rust and apply some anti corrosion.

It is a tight fit but I smeared some silicone grease on the rubber and it did re-locate.
