The Pinouts for the cruise control module in an EB2 Fairy/ghia

anyone know them?

after transplanting the system into my eb2gli have a spare brown wire (no trace) that used to do something that isnt listed in gregories and a cruise computer that wont hold speed

any help plz

There is NO brown wire but there is a brown wire with a black trace that goes to the pneumatic control unit and without it it will not hold speed. I have the genuine manual so if you need any more diagnostic details PM me.

ok found where the brown wire goes, and it still isnt playing ball, if i run power to the vacuum unit manually i can get it to work so it has to be a switch/sensor/electronic problem.

any test tips/suggestions?
