Where would be the best place to take off a 12v supply which will be on a 15A fuse, relay, on a 10A rated electric pump?

Looking for somewhere suitable in the engine bay so I don't need to run a new line from the battery.

Many thanks for your ideas.

 

The electrical box on the passenger side has a stud near the bottom that is the direct feed to that box. A ring terminal, and proper in-line fuse will do what you wish.

 

Exactly what I'm after. Perfect and many thanks.

 

I will second that, exactly what I did. Put an inline fuse right by that terminal just in case.
