Adapter Recommendation for Going From 7-Way Round to 7-Way Blade
Question:

asked by: Gary
Expert Reply:
We have an adapter to go from a 7-Way round pin on a tow vehicle to a 7-Way blade style on a trailer. You could use the # HM47425. This would work well for you if your tractor has trailer wiring setup for combined turn signals where the blinkers and stoplights are on the same circuit.
If they are separate then you would need to install a second 7-way blade as that would be the easiest way. For that you would need a 7-way like part # 37185 and a signal converter like part # RM-732.
