I took a tekonsha voyager out of my brothers van, and am trying to hook it up to the factory pigtail/harness on my 2006 taco with the tow package. Theres 4 wires coming out of the tekonsha, and 5 wires on the harness. heres some pics of them and the wiring explanation. A little confused on which ones to connect, and which one will not be connected. Any help is appreciated! trying to tow the trailer this afternoon.

looks to me like the green wire to the running lights is not used in your application. YMMV, Maybe a support call to Tekonsha is in order?

Exactly. Not all brake controllers have a wire for the lights, and that's fine.
