Problem with trailer lights on 2014 Yaris

Just to verify your wiring to the 6 pin connectors for the tail lights:

Pin 1 - Blue: Stop Light
Pin 2 - Sky blue (Right) or Yellow (Left): Turn signal
Pin 3 -
Pin 4 - Green:Tail Light
Pin 5 - Red: Back up
Pin 6 - White/black: Ground

How are you feeding the switched power?

I'm not using switched power nor have I found the connector you listed. Where is it? I'd simply download a schematic, but every damned page wants credit card verification; my first born; or a commitment to purchase a timeshare in Tuvalu.

Currently I'm tapping off the wires on the left tail light assembly, with one wire of the converter traversing over to the right tail light for the right turn signal. It's not rocket science and a similar 5to4 converter worked on my 2008 Yaris, tho the tail light assembly was completely different. Nevertheless, on that vehicle I simply found the lines, tied them to the converter, tied the converter ground to the chassis, and it worked.

I have a 3-door hatchback. I'm assuming that the multiple wht/blk wires going to the various bulbs are all tied together at some point, and thus my decision to use just one of them ( from the brake light bulb ) should work just fine.

I guess my basic questions are this:

1) Are all the wht/blk lines on each bulb common? If so, why don't they ohm out to chassis ground?
2) Will a standard 5 to 4 converter work?


Why does this have to be so difficult? Did I purchase a dead converter ?
