4 Prong to 5 Prong

[waterskiercu]

Looking at buying a new car to tow the boat -- came across a Telluride that my wife likes and is rated for 5K lbs. which is more than enough to yank a Sporty a few times a year. Unlike most modern SUV/trucks that come with the circular trailer prong, the Telluride comes with the old school 4 prong. My question is, is that an easy fix to convert a 4 to a 5??? I probably wouldn't monkey with it but maybe the dealership could knock it out or take it over to UHaul. Thanks in advance.

Are you talking about converting the vehicle side to a flat five prong? If so, then you need this. The blue wire needs to tie into your reverse lights so the trailer brakes release.

I was going to suggest just getting the factory 7 pin adapter - but it looks like they recalled them all

Is the Kia you’re looking at a new one?  I found a discussion from 2020 in a Telluride forum that described a 12 pin connector under the truck behind the spare tire that is what feeds the trailer hitch connector.  Pin 8 in that connector needs to be populated with a wire then you should be able to install a 5 pin or 7 pin round connector to give you what you need.

Thanks. We ended up passing on the Telluride -- later found out that the airbags had been deployed. Ended up going with a Honda Ridgeline which has the adapter built in. Hoping it can handle yanking the boat -- says 5000 towing. Boat dry plus trailer should be around 4000.

Sportster?  Should be fine.
