I am guessing the bulb goes in where my thumb is. I am not sure where the blue wire that goes to Speedo should attach. I have no recollection if I ever had a bulb in here. I don't remember ever taking one out.
I bought a few festoon 12v bulbs and none of them fit inside.
Do any of you all have this Speedo or can go some input.
As always thank you!
