Inner Edge wiring question

[GranPrix]

I have a I01UF7L seven lighthead model with the two halogen wig wags/td and I have three plugs not connected to anything. Does anyone know what these are for? The pic shows one side. The other plug has the same yellow and green wires in addition to a white and green wire.

Is there a chance the same board and wiring were also used in the ten-lighthead variety?

Possibly

There's an old version of the installation guide here:

The two WHT/YEL and YELLOW connectors are meant to be swapped in if you need a steady burn module on either side, and the WHT/GRN and GREEN connector is if you have a split center module.

Do you think it's possible to swap out the MR8's for LR11's?
