JZA70 Cruise Control Parts?

[Endless]

I'm currently doing a manual conversion on the JZA and have come across these two boxes as i was taking out the brake pedal assembly/cage..

First was this one 'OK Monitor' attached to the side of the brake pedal cage by a extra metal arm.



Has a 5 pin connector on the rear.



Then this labeled 'Speed Control' hanging just above the brake pedal which i had to remove to get to one of the top bolts.



Am i right in thinking these are both to do with the factory Cruise Control? Has anyone come across them/had experience with them before?

I have removed the mechanical side of the cruise control so no worries if they are just part of the electrical side, just thought i would ask!

"Speed Control" is definitely the cruise control ecu.

NFI on the other though
