No need for any programming if you just need a 4-pin (no brakes) connection as long as you don't mind the reverse alerts when backing up with a trailer. $40 module from Amazon & I used a Curt receiver. But as far as Forscan goes, I do not believe you can do any programming if adding a factory plug.
I like the wider stance for better stability, especially since I narrowed the tires a tad from stock. The added poke using 1.25" spacers is not noticeable to the untrained eye, which is what I wanted.
