They showed me the memo stating there were occasional problems installing the other way and to wait for the kit so ill wait.
Occasional problems...hmmm..I would guess 2 to 4 million trucks sold...I wonder how many make occasional. Anyway, good luck with your install. Since the kit was supposed to be available last fall, whats another couple of months wait right?
For what its worth, no one on here has reported problems after installing the OEM controller on a truck that didn't have it. Mine didn't have it installed either, I got the part numbers and the EVIC code, went to the sales manager where I bought the truck...he ordered the parts through the parts department and within two weeks I installed the parts and had it flashed for the EVIC display. I have to tow and simply couldn't wait for a supposed "kit" to be made available. You will read more success stories on here than failures.
