The X-01 just represents the wire or harness, it isn't anything on the car. The wires must be damaged or you are testing the wrong connector. Have you tried new bulbs?
i tested everything on bumper side with the continuity setting on my multimeter, reading shows all good,
and i tested relay and switch for voltage all good ,and both relay + switch functions as i click them
but when i test the E7-03 connector(located near the windshield washer fluid that connects bumper side and engine bay side) both wires shows no voltage at all
so it must be something in between E7-03 and relay which is the wiring hidden behind radiator and headlights
(if u say E-01 is nothing, can i just reroute a new wire from relay toward the E7-03 connector? )
the fuse box only the bottom fog light fuse has constant 12volt no matter the car is on/off on its right pin, the top one doesnt have any voltage no matter car on/off switch on/off
does it work like this? or the top one suppose to have 12volt going through them when foglight switch clicked? (could anyone do voltage reading on this fuse when u turn on the foglight?)
