2017 Ridgeline Trailer wiring 7 pin round to 4 pin flat
 

I'm trying to find the right adapter (if one exists) to be able to plug my 4 pin flat plug from my trailer into the 7 pin round plug on the Ridgeline. Any help would be appreciated. Thanks!

Hi, Brian...I'm new to this forum, but I read your post and did a little searching.
Don't know if you solved your trailer harness problem, but here is a link to a site that appears to have an adapter
for a 7 pin to 4 pin trailer wiring hook-up (specifically for a 2017 Ridgeline). It's the sixth item from the top of the page...
hope this helps!

I purchased this one from Amazon but it is available from Walmart too.
