This kit is great if you can get it installed correctly. I'm an engineer so I've got a technical mind and many years of experience servicing my vehicles. I still found this kit to be slightly difficult to install due to bulldog directions being wrong or unclear. This was installed on a 2002 dodge dakota quad cab. One of the ignition wires said it required a relay but I read from several sources that the ignition 3 wire was not required. I called tech support to confirm and they agreed, so I wasted 10 bucks on a relay and additional wiring, oh well I'll use it in another project.
