questions about battery disconnect wiring

@Mattax Thanks very much for the reply.
I’m not skilled enough to draw out my wiring. I’m just trying to get the battery in the trunk in a better way than the minimum NHRA requires. I get it that my wiring has been modified because of the ammeter delete.
If you could do me one last favor and tell me what I should use instead of the 24059, I’m outta here!
You’ve been more than helpful. Thank you.
