retrofit 3rd gen tow adapter?

Anyone done this?
Installed a steel high clearance rear bumper, but the cutout (for tow plug) fits 3rd gen.
I've heard the solution to this, is to retrofit a 3rd gen unit, which is supposedly easy.

For now I've wrapped up my OE part with electrical tape and ziptied it hidden away, until I figure out a fix. So for now, it's not "usable"

Anyone ever done it? How'd you do it?

I think it might not even be proprietary to the 3rd gen, as there's many that look just like this as a $40 kit on Amazon

I might be in this boat soon myself.

 

There's a lot of adapters out there that will tie right in to your tow plug pigtails. Definitely not a proprietary design to Toyota.

If you can find a way to keep the 2nd Gen plug, you can just use a tow plug adapter.
