I see that my oil temp and carb temp senders each have two seemingly identical leads and assume one of the wires is a ground. So, do folks bother taking these all the way to the ground block, or are they simply grounded locally to the engine? If so, to what specifically? I know this is a small thing, but this project is nothing but small things now -- hundreds of them. ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
