which wire is live(colour) i need to check mine as the heater comes on full every now and then but i do seem to have some control.I therefore think my control module is ok and the valve(driver) is sticky and stays open now and then

connect the clamp of the test light at the pole of the jump start pole (Plus)
Then 'inject' the needle of the test light into the cable yellow/brown for the driver side and yellow/purple (violet) for the passenger side, then the light will blink according to the impulses or it will be full on at the 16 degree Celsius position, and it will be off at the maxiumum temperature adjustment of 28 degree Celsius.
