'91 plug wire replacement

I'm an old duffer trying to help my son get his '91 4 Cyl. Corsica running better. It needs new plugs and plug wires. The spark plugs are right out front, but how the hell do you get to the other end of the plug wires? Does anyone have a tip on doing that without disassembling the engine or removing it?

It's a pain at first, but it's not too bad. Reach from the drivers side of the car towards the center not far below the head. You can see the coils if once you know exactly where they are. Be careful not to mix up the wires or you'll have to change them. If you have a haynes manual or something like that follow which plug goes to to which coil.
