Bulbs and placement?

[wildone454]

Which bulbs go to what? And where do they go into the cluster? I think the grey wire one isn’t it for the heater backing light? If so it should plug in to the back of the heater controls correct?

I would Imagine it depends on what you are working on and what bulbs you are trying to use.
