Greetings, the order of ignition in a 4 -cylinder engine is normally 1,3,4,2 (except for certain cases such as the beetle), although the engine is arranged linearily 1,2,3,4 the ignition sequence is not, in the case of the KA it has two coils integrated into a only piece, call for the example of coil A and B, they are always activated in sequence A, B, B, B, B, B, B, B, B, B. The connection of the spark plugs to coil A is 1 and 4, and in B is 2-3, in such a way that the sequence 1,3,4,2 is met. To discover what is the A or B coil, try to measure the resistance of it where the connected cables go, where you get impedance reading that is one of the coils.
