Yes, I lose the ASF and the AFS OFF light will always on now. I'm considering what can I do to stop that.That makes more sense. I was pretty sure most people who had done the mid cycle refresh to their 08-11s said you had to replace the bumper and grill to get proper fitment of the 13-15 lights on the 08-11 models. Also from those threads, i believe there were some wiring differences. Do all your headlight functions work? I guess you lose AFS with this no matter what. That might have been the biggest of the wiring issues.
Looks pretty good, if you were going to do this, and get a off road bumper, probably be a good idea to just order a salvaged 2013-15 bumper and grill and update the whole look.
