Ez wiring for 73 duster

I have installed an aftermarket wiring kit in an old mustang for my bud. [got it from speedway motors in Lincoln NE] The kits are very good for the most part but be careful as to the compatibility of various components {a good example would be the ignition switch} make sure you can make it all work with what you have. You'll need some good skille and some good tools but it is very doable. There is a wiring book that you can buy by a guy with the last name Candela that is very good and I would recommend it. Bought mine at Barnes and Noble's. He has all the tips that are important for a goos job.
