uch bracket/earth

[decco]

Can anyone tell me if the bracket for the uch is also an earth for it please before i start dismantling things ? The only reason i ask is my lights flicker when i turn the car on but it stops when i move the uch on the bracket

It isn't, will be a loose relay or connection.
