The Kat's Heaters # KH11486 Frost Plug heater would be compatible with your 2009 Wrangler with the 3.8L V6 engine. It installs into the frost plug location at the rear left of the engine (see diagram). The existing frost plug would be pried off, and the heater would be installed in its place. The Phillips screw on the heater would be snugged down to get a tight fit.
Like any modern engine, the space in the engine compartment as at a premium. Kat's tells me that the frost plug removal and heater installation might be easier to preform from under the vehicle. How difficult you find the installation will depend on your mechanical ability, but all in all I wouldn't consider the installation too terribly difficult.

1) Wranglers do not have transverse engines. 2) If you ignore problem #1, the right(passenger) rear core plug is inside the catalytic converter heat shield, while the left(driver) rear and center plugs interferes with the starter. 3) Jeep installed them in the right (passenger) center freeze/core plug location.
