Battery relocated to trunk, inertia switch?

For what it's worth, I have a Cole Hersee 24200 that I bought before I found the Parallax relay. It is a dead ringer for the relay in the Painless kit. Even the printing on the bottom that is easier to see when zoomed in using the Summit kit. Not saying I can read the text in the image, only that it is close enough that I think it says 24200 and 12VO46M just like the one in my hand. Even the same brass nuts and white insulators.
