There is a 1 inch by 1.5 inch fuse box with clear plastic screw-on cover to the inside of the main fuse box of my 88 535is. It has two 25 amp fuses and a red and green wires coming from the main wire harness. These fuses do not appear to go to anything. Are these for some accessory I do not have or are they extra? Does anybody have these functioning on their cars? I was thinking of modifying them to accept the mini blade type fuse and using it for the AC fan-melting terminal culprit.
