Am loving working through these issues, I hope being a complete info sponge isnt too annoying to y'all..? After I (we) fixed the fluid reservoir I moved on to the issue of flashing brake lights = easily fixed by cleanign the contacts in the light housing. But before i took out the housing i removed the boot carpet and found a cable that seemed to go nowhere. I took a photo - see attached images. Any thoughts..? As always - mucho appreciado hombres
