trailer wiring diagram

I just bought a 2006 tacoma. It does not have the factory towing package.
It does have an aftermarket hitch and 7 blade electrical hookup.The 7 blade hookup did not work.I replaced the converter and it still does not work.Both of these converters have a wire that goes to the battery. I would like to know if anyone can send me a diagram showing how to properly hook up this converter.When I checked the output on the 7 blades, the left turn/stop light has 12.5volts all the time, without the turn signal on or the brake on.

 

here's a link to some wiring diagrams. Between that and the convertor's instruction sheet, you should be able to figure it out.

 

I'd ditch it and get a new plug'n play model to avoid chasing gremlins wasting time.
