Spare 15 fuse in #1 slot on Bobcat CT 235 fuse pannel

[powerscol]

Has anyone used this fuse and is the wiring there. Picture is on PM-34. Just wondering before I try and pull the block to find out. I'm looking for a 15 amp hot with switch on. Also there is a pigtail at the rear that my work light plugs into. Anyone know what fuse it uses. If not Ill pull the fuses one by one to find out. I am a bumble finger guy and hope not to screw up the wiring.

Thanks
