Nah, sorry, no idea what it is, I guess nobody else knows either.

Bigger picture:

My dash display is wonky, if it is cold it can take up to 15mins to come on, if it is warm and sunny out it will take a few minutes the first time you run the car but will come on instantly the rest of the day.

After much messing about, research and discussions with folk who know a bit about electrics I figure it's a resistance issue as resistance is affected by temperature.

It may be a circuit component within the display that needs replaced but I am trying to check the rest of the system before I go forking out, this particular earth has me interested because the display pin outs have both an earth and an electronic earth listed.

In my belief, if it isn't a board component in the display unit, it is most likely to be an earth. There seems to be a gradual fading of the permanent positive feed after the car has been parked.
Since temperature affects it I am hunting the engine bay and this one sticks out as being pretty individual.

Most likely a circuit component but I just want to draw a line under this bit of investigation before I go for a new/repaired display.

Agreed it may be a radio suppressor but these days I wouldn't have thought it necessary given the use of resistor type spark plugs.
