I just did this on my 350f.. I had no previous experience before doing it. It's not as hard as it seems.
If you have the stock coils I don't think you can change the wires since they are integrated. Thats how it was on mine at least. I would recommend getting a new pair of coils from DCC and be done with that. Also you can either get one of their wire kits which includes coil boots, clips and sparkplug boots. Or you can get wires and the accessories from somewhere else. That being said, on to the how to..
First, mount your coils in the desired location. From there you need to run your wires how you want them and mark the wire about a inch longer than where you want it. Cut it. Repeat to other wire. From here you should have two wires with the spark plug boots on one end and a cut end on the other. Slide the coil boots on (you can use some silicone or spit like I did to help them slide) Now you have to cut the rubber and insulation back from the cut end. Trim this to about 3/8". There is the rubber then a white layer(this is how my wires were) and then the copper or graphite wire in the middle. Do NOT CUT that, so be very careful especially with the graphite core! I used a brand new razor blade to cut mine, that way i didnt have to put much pressure on the rubber for it to cut I just slide it over the rubber and it slices away. Next you want to bend the wire core over and onto the rubber, then you want to slide the metal clips on the folded over core. Use the opened up side not the side that is a complete circle cause this end goes into the coils. Once you have the clip over the wire core bend the tabs over with some pliers just enough to it will stay on and the coil doesn't slip out. Then get a pair of good wire crimps(then kind on the handle side of the big electrical pliers that is for big crimping) and crimp the clip on to the rubber so it is nice and tight. DON"T over do it! Also, make sure the part on the pliers that has the hump that crimps, put that on the side that isn't the open part on the clips.
From here you can take the coils off and push the metal clips in and slide the boots up and remount or if you can get to them with out taking the coils off do that.
Hope this helps, good luck.
