In the process of putting cruise into a 5 spd 91 245. Have a complete setup and I've seen this group of parts in 90 and later...I think. Unfortunately it's been sitting for quite some time. Labels are uninteligible...as is my memory. Eight wire brain, vacuum motor, servo for pedal, two pedal switches in series, stalk, etc. Having trouble with three remaining wires as they don't match Bentley diagrams and Bentley only shows cruise in 90 and up. Perhaps this setup I have is pre-90. I have a yellow wire from the box. Seems this should connect to the blue/black wire from the instrument cluster large plug (speed signal?). Then there is a blue/red wire. Seems that should plumb into the switches, but uncertain how. This lead is very long and has a female spade junction in the middle. Last is a blue/yellow wire...no clue on that. Can someone help me get this cleared up? All other parts and wires are in and connected.

Thanks,

DS
