Haven't hears of either. Well, outside of that one company promising unicorn parts upgrades.
Pioneer doesn't need the i4wd override.
Talon 4x4 is electronically controlled. Pioneer is manual cable operated.
When a Talon loses i4wd, sometimes they are stuck in 2x4. Pioneer will keep 4x4 irrelevant to the i4wd status because it's manual.
So for a Pioneer, you dont need a "override" you just need a "disable". It could be done by killing the engagement sensor line or fuse.
