Had this on my '07 with a 4.0L.
It comes with a switch blank cut and fitted with switch. It is currently programmed for AFE Stage 2 CAI and cat back exhaust. $400 (including shipping) OBO.
I noticed the difference most when I was towing. I towed my 1940 Chrysler with a big block on my double axle trailer from AZ to OR. If someone thinks the price is too high, feel free to make an offer. I am willing to take a partial trade for a couple items from CTD plus $.
That is the correct #. Picture is not of the same one, it has separated plugs instead of the one big plug.
Sorry it took me a bit to reply, had surgery yesterday and they flubbed on the anesthesia and it still has me a little bit off.
