Evening all , my abs light is on and while installing the carpets I wondered if I might have reconnected the rear two incorrectly. I don’t think I have but wondered if this would cause it?

 

It was fine before the carpets?

 

not sure on that. Cars undergone a major restoration. All sensors have been replaced with”used good ones” . Carpets aren’t relevant other than I don’t want to fit them and then pull them back out if not connected right way. Just trying to rule something out while I’m fitting the carpets! Going to check the fuse first I think
