Spark plug wire diagram and coil firing

I have had trouble with my engine misfiring so I did the basic tune up repairs. Wires, fuel filter. And that did not work so I took it to a local mechanic to have it diagnosed. They told me the coil was bad and it would be a $250.00 repair. So I decided to do it myself because the part was only $82.00. I changed the old one out and put it back together exactly as I took it apart. The engine still misfires and the check engine light still comes on. I did notice however that the wires seemed to be in the wrong order so I am hoping you give me advice on what I may try next and also a diagram of how the plug wires go and what order they plug onto the coil.
thanks

Good day, I have found a new problem that is toggling my brain. One of my pistons close to the coil pack has stopped firing completely. We have swopped wires and plugs. They do work. I have spark on the spark plug and is working. The compression is good. But not firing, we have confirmed by test that the coil pack is not the fault. There is n ticking sound on the injector. Is there a other way of checking if the injector is working or getting power. Please help. Car is running high on petrol usage.
