Review on TOYOTA Genuine Accessories 08921 35870 Converter by Mike Larkin

Just the thing! Works perfectly! There are no instructions, but everything is pretty obvious. The only odd thing was the little gray box they sent with the box. I have no idea what it is? Maybe a relay or something? I was about to throw it away, but then figured out where it went and easily replaced the old one (regardless of whether it needed replacing or not). the side attached to the left wall. You'll have to lie on your back behind the pedals to get there, but this is an easy replacement. One screw and quick electrical connection. If you need a new trailer wiring kit, get this one.
