Converting Separate Trailer Wiring to Combined for Wiring 7-Way to School Bus

Question:

I have a 2007 ce 300 international school bus. Im trying to hook up a 7 pin vehicle side connector so I will be able to use the curt c5118 wireless proportional brake controller. The issue Im having is my brake lights and turn signal light so not come from the same wire as is suggested in most 7 pin instructions can you please advise how I should proceed. Thank you so much

Trailer wiring normally has the stoplight and turn signals on the same circuit which isn't always the way vehicle taillights are wired. In those situations you need to use a signal converter like part # RM-732 to convert the separate wires to the combined setup which would work great on your 7-way to be used with the Curt Echo Mobile # C51180.
