What are the green connectors behind cluster

[motorsports_3]

While removing my dash, i had to rmeove the cluster. I dissconected a White, blue and yellow connector. There are a bunch of green connectors in the middle that dont have anthing going to them. What are they for?
JIC my car is an 88 325e. TIA

if they are behind the speedo they are connections for cruise control i was told

however i only had one wire mated up to my e30 cluster with cruise and that wire was for the speedo signal

it is for the cruise if its right behind the speedo. no idea of its purpose. i knew at one point.

Oh perfect, I only had one wire also, and no cruise control, so I dont have to worry so much. Thank you guys.

the large green connector that is the same size as the white and blue ones, is for the on board computer. The small single pin green connector that goes to the bottom of the speedometer is the speed input for the cruise control.
