Although I also wouldn't order radio stuff from quadratec.
I believe the 140 one comes with the plug and play harness for the Jeep as well so all you do is install it and don't have to splice wires together.
If you buy the individual parts then find out you also need to buy the Jeep side harness figure another 25ish for that and your right back at 140 except you have to make all your connections.
It may be a typo on their site that doesn't list the plug and play harness on the product details page, If you look at say the Kenwood kit Kenwood w/install kit
it lists the plug and play harness as opposed to just the wiring pigtail
