Wiring for 7-Pin Round to 7-Blade Adapter
Updated 07/23/2019 | Published 07/22/2019
Question:
I need to be able to adapt from the 7-round pin trailer connector on a friends Prevost motorhome to 7-blade pin plug on my Roadmaster 146-7 umbilical cord that I use to connect my motorhome to my tow car. Is there a wiring diagram available for this adapter to show how the round pins are wired to the blade pins so I cab be assured that this would be a straight through adapter with no re-wiring needed? Thanks!

There is not a wiring diagram for the Hopkins Trailer Connector Adapter - 7-Pole Round Pin to 7-Pole RV # HM47425 but I have added a photo showing the functions of a 7-pin round and 7-way RV blade style, which is what this adapter was intended for. The wires will match the functions shown without any type of re-wiring needed. The only thing you need to be sure of is that you have the same 7-way connectors, and if you do it is assured this adapter will work.
I have added a link to a video review for you to take a look at as well.
