Adapter for 7-Way Blade Trailer Connector to 7-Way Round Trailer Connector
Question:
I have a newer model GMC pickup and I want to be able to move Ag equipment like wagons and tillage equipment including their rear turn lights, tail lights, and brake lights. I know my truck has a 7 pin flat and all my ag equipment has 7 pin round pin, but within the 7 flat it uses a 3 wire rear light control and 7 round use 4 wire rear light control. Does anyone make an adapter for that?

Expert Reply:
There is an adapter for you that will allow the 7-way blade connector (sometimes called a 7-way flat) on your GMC truck to work with the 7-way round connector on your trailer. If you take a look at the accompanying photo, that's what your connectors should look like; if so you will simply need Adapter # F77R and you'll be set!
I have added a link to a video review of this adapter for you to check out as well.
