#7 is the second to last back cylinder on the drivers side. Remove the plug off the coil, remove one 7mm or 8mm bolt that holds it down to the manifold. Just pull it straight up, add dielectric grease to the bottom of the spring on the new coil and slide it down till it bottoms out. Replace bolt and plug then fire it up. 9 out of 10 times its the coil that misfires and not a plug issue so you should be good to go with just a coil swap.
