LG on the back of the Instrument Cluster

as in the title what does the LG connections (as labeled on the flex circuit bord on the back that the gauges connect to by screws) go to? it only is on the speedo, Tach, and fuel gauge. is this a special ground that goes through the ECU? or does it stand for Large Ground? thanks for the help and info.

It means Long Ground

Thanks for the reply!

Electrically how is that different from the other GND markings on the other gauges? Why do they have a regular GND wire and a Long Ground? Do you know if it’s because of a load reasoning or because the wire is longer due to the location of the sensors and is a longer distance then what should be used on the other gauges?

Can I run all the gauges off one large gauge wire directly grounded to the battery?
