    So the one with 2 wires is the clutch switch and on OP COM is always active, no mater if the clutch pedal is pushed or not...So I guess it's his fault why CC doesn't work?

    You can check input/output voltages to the switch,but can you confirm that you set cruise to present in the CIM ECM and IPC ?

    Ive seen a bug in opcom which means the switch never changes in measuring blocks but cant remember what model/engine the bug was in.

    Id be temped to check the signal at the ecu using back pin probes.

    I have some very think needle probes which you can slide into the back of any connector under the rubber gromits and make contact with the pin while its connected. you cam use very narrow sowing needles too. You will have to remove the back of the ecu plug to get at the pins.

    Another alternative which i dont recommend is attach a small sowing needle to the multimeter red wire ising connector block and lightly pierce the wire. Then put some silicone on the hole afterwards.

    Will bridging the pins not bypass the clutch switch? This way if the CC starts working you know it's the switch

    Depends in whether pressing the pedal opens the switch contacts or closes them.

    If he is going to unplug the clutch switch it is just as easy to check the operation if the switch when it us unplugged.

    Yes. If he disconnects the brake switch then connects opcom and looks for a change when he bridges the 2 pin connector this will confirm if the switch is at fault. Obviously if it changes a new switch would be needed but usually they throw P0704 (from memory) when there is no signal which is what makes me think about software bugs.
