The WOT box works very well and is easy...way easy to install. There are if I remember right 5 wires to hook up two under the hood one for the clutch switch and two at the computer harness. The two at the computer are a bit difficult because it is akward working behind the passenger kick panel there just isnt much wire length to make the soldering easier. But other than those two wires it was a snap. I took about 1.5-2 hours doing it but alot of this time was used to route and hide my wires. The instructions that come with the box are specific for our cars. They have colored pictures making it something a 8th grader could do.
