i wonder how many cables should there be from the cnock sensor behind the engine?I wonder because i found 2 cables next to the cnock sensor behind the engine.one light brown and the other black and white.Which were cut off and put to gether.former owner has replaced the sensor,but i dont think it is the orginal one,because the blue cable has ben cut off and put to gether with the new sensor.i bought my syclone one year ago,and i have had some problems with it from the start.it doesent seams to run well.i would appreciate som advice.thanks
