I need your help findind a proper fuse location

Hello electrical gurus!

I am trying to activate the backlight on my Baja designs S8 Bar that I have in the bed of my truck, and in the front bumper at the same time. I have already put wiring harnesses in place so just need to find the fuse to use. The entire

I want/need to use a fuse under the hood that is NOT the IGN 10amp in the fuse box. The reason being that fuse is already occupied and powers on my Switch Pro SP9100. I run all of my lights from this SP9100 and I rather not mess with it. Additionally the SP9100 is taken up and I cant wire it to one of those switches.

I tried the empty slots in the fuse box to see which was IGN power or ACC power and I could not find any additional other than the mentioned IGN fuse.

Any tips would be really appreciated.

 

How about switching a relay with your parking light circuit? Then you could pull power from a constant source, while switching it with your parking lights.

Or, repurpose your cargo light switch? Unless you actually use your cargo light…

 

I do use it. I’m trying to find an easy way to do this with an add a fuse and call it done. Just having a hard time finding which one to tap onto.
