I know your probably looking for more details than this but here is some info and location pictures.
It is from my Multipoint upgrade thread, (the never ending story)

Well like most days, I did NOT get much accomplished today.
So here is what was taken care of.
I had to relocate just a little bit my 12volt socket, it was (and still is) located under the tank next to my Stebel air horn.
Here is what it looked like before.

Your going to have to imagine this just a little bit here, this is exactly the mounting location of the Stebel on the next step when I re-do the wires for the stebel I found a way I like the look of better than what I had started with on this project list.

You can see the bracket for the stebel still in place.

And here are a couple pictures of what I did to freshen up the 12volt weather proof socket and move it down a littel bit hidden back in a little farther and then bent the bracket to tilt it a little bit to make it a little easier to access.


I ended up actually attaching mine to a switched position on my auxilary fused power panel I installed on my long arse list of stuff done.
