I am tracing down an issue where I have a lack of power on the RED/YELLOW wire that runs, among many things, my evap sensor which is throwing a code from this wire not having 12v like it should. It splits to a bunch of stuff through a connection called S155 (what/where?), but what I am trying to find is the fuse at battery junction box seen below. It shows violet in and red - red/yellow - violet/white out. 3 fuses total.

I looked in the engine compartment by the coolant but there relay box there is not fused.

I am looking for a battery junction box with three fuses and one violet wire in, three out colors listed above.
