This is the best $20 I have ever spent when it comes to tools for my car. For those of you who are "Attention Deficit Disorder" like me and forget what the hell you were looking for in the first place when you get to the other point in a wiring diagram this is a great help. Its all correctly color coded, all on the same page and laminated so you can mark stuff with an erasable marker. Way more fun that decoding that mess out of the manuals.
