The brand X kit is not even close to the exact same......

That kit uses a generic solenoid bracket which you will need to find a place to mount, it uses a seperate nozzle assembly that requires you to drill a hole in your intake tube and run 2 hoses to it. It also comes with NO bottle heater, No fuel line adapter, No TPS switch (WOT switch won't work on the Jeep), NO window switch or progressive controller.....

The Brand X accessory kit is $380, and still doesn't include the TPS switch or controller......those will run you another $250-$400. Then you need a remote bottle opener, and 1 step colder spark plugs too.

Even if you buy the Brand X kit, you're looking at anywhere between $1200-$1400 to get a complete kit.
