I have the Prodigy P2 on mine and it has been a good controller. My Pilot didn't have the wiring harness so I had to wire it in myself, but got it all in, but if you are buying a new Jeep you should be good to just plug in and mount your controller. I am sure if you are a member in the Jeep forum they have some threads on it.
If you are picking it up with the Tacoma you will have to buy a wiring kit for the Tacoma and then one for your Jeep. How far is the dealer from where you live? Maybe work it in with the deal to just have the dealer just deliver it to your house?
