Me thinks that this is too good to be true but ... do 9-3s come wired up for cruise control, the only action required being to fit a new left hand stalk with the cruise control, uh, control?
Thanks in advance. Tim
Others will have to give you the definitive answer; but it is common for wiring looms (ie, the full set of cabling in a machine
-- here, a 9-3) to be made in as few versions as possible. The extra cost of adding wires which may never be used is offset by cheaper design, drawings, production lines, inventory handling and such. There may even be eventual unexpected use of them. So it is possible only the wires exist, taped back out of the way.

A Saab using the Trionic 7 engine control system (all petrol versions of the 9-5 and the late years of the old style 9-3) has a drive-by-wire throttle and this makes it very easy to implement the cruise control in software inside the Trionic 7 computer. The only non-software parts of the cruise control is the controls on the left hand stalk, indicator bulb/LED in instrument cluster, safety switches on brake and clutch pedals and some wires. The only part missing on cars without cruise control is the cruise control version of the left hand stalk.
