How to connect the distributer wiring? Opel kadet 1.6

Put the car Crankshaft maker for ignition timing at TDC. You need to know number one cylinder is on ignition fire position. You can do this by looking at the valve positions generally last end cylinders no 1 and 4 will be looked at. No one fire position is when number four Valves are on the rock. ie inlet and exhaust are rocking. This being certain put the distributor in place so the arm or Rotor Arm is pointing to a contact in the cap. This will be number One firing. Now you know this you need to understand that there are two possible firing orders. 1342 or 1243 on fords. The most important bit is knowing the direction of Rotor Arm. Normally anit clockwise. Number one is at the front or near the radiator if transverse engine or near the crankshaft other end of gearbox. The cylinders on the engine count 1234 then put the leads in order or say 1342 So number one goes to number one cylinder then the next lead on the distributor in the direction of travel anti clockwise will be Number 3 cylinder then number 4 then last is number 2. Firing has to be before top dead centre normally about 6 degrees. With the distributor in place make sure the lobe opens the contacts. The point at which these contacts open is the spark. The charge inside the coil releases as the points open. The collapse of the electrical field inside the coil is what provides the spark. Hope this help you some engines had a key way for the distributor drive others had a helical gear.
