ya you need a indicator stalk with cruise control buttons on and a brake pedal switch
you can buy both from LMF vauxhall or the stealership if your feeling flush
STALK
fitting is quite simple first remove the steering wheel surround. couple of screws and plastic clips.
you"ll need to move the steering wheel from left to right to see the clips
once the covers removed the indicator stalk is held on by two screws and a multi plug. remove it.
you will also notice an unused single black plug with a blue cap sitting next to the stalk this is for the cruise control
when fitting the new C/C stalk simply remove the blue cap and plug the unused wire into the extra socket on the stalk ( job done)
PEDAL SWITCH
you"ll need to remove the cover infront of the pedals (plastic screws just twist off)
once this is out of the way you will see a plastic heater pipe this just pops off
now you should have good axcess to the pedals notice the clutch already has a switch fitted
so just the brake to do .
above the brake pedal you will find a white plug taped to the main wiring out of the way cut the tape off
and pull it free ( be carefull tho)
the back ove the pedal has a square cut out for the switch to fit in (only goes in one way ) push in untill it clicks push the plug into the switch. pump the brake pedal with your hand to make sure the switch is fitted securly then take for test drive before refitting everything.
its bin a while but im sure i havnt forgot anything hope you find this usefull
