Electrical Questions (speedo and trim/drive)

[boomer35]

I have a gaffirg speedo with a light on it... the light has 2 wires, one that goes right into the light, and one that mounts at the end of the light (i assume ground) they connect over to the RPM gauge....

can anyone confirm if thats the ground.... also, when i jump it to the RPM gauge, where does the other wire connect to on the RPM gauge?

next on my trim and drive indicator i have two wires, one that must be a ground. Both hook up to the other RPM gauge, where do those go?

THANKS-

boomer Check this link out it shows the light ( black and white wire). Generally the lights are all daisy chained together from the source (power & gnd) from light to light.
