Review of the Hopkins Endurance Twist Mount 7-Way RV Trailer Connector


Speaker 1: Today, we're going to take a look at the Hopkins Endurance twist mount 7-way RV trailer Connector, part number HM40930. This is what the connector looks like once installed on the truck. This fits all Chevrolet and GMC trucks that have this style hitch and this bracket right here.Now this is a great replacement for your original connector, like this one right here, which is getting sun damage, and the plastic get brittle over time. Or a lot of times, I see these guys just smashed. One thing you really don't see, it's hard to tell, but inside these pins here, you'll end up getting with corrosion inside there. At that point, there's nothing that you can do but replace it, and that's where Hopkins part comes into play.Same as the original connector.

It's a seven-pin connector with flat pins. Of course, you got your round pin the middle for your reverse light circuit. Same key way, so it works with all 7-pole connectors that are out there. Has a lid that snaps tight. It also has a little seal around the edge to help protect it from the elements.Now our entire housing for our 7-pole connector, is created from ABS plastic.

Of course, though, except the internals, where the metal is needed. Let's take a look at the back side here. You can see where our factory wire harness plugs right into it. So it's very easy to install. No cutting or splicing.

It's designed to be a direct factory replacement. Now's the time to go ahead and try it out and test it.You at home, would probably use a test light, or just use your trailer to make sure everything works. I don't have a trailer handy, so I'm going to use one of my testers from my shop. First off, we have a running light circuit, our left turn signal, our right turn signal. Let's check our brake signal, which we should have a constant output on our left and right turn.

Okay. Now we'll try our brake controller, make sure the output there.And we'll also look for a reverse light circuit. Finally, we'll double check for our 12 volt power that goes out to our trailer for various accessories. And we've got battery power there. Now to give you something to compare it to, such as a Pollack twist in 7-pole RV style trailer connector, part number PK11916. There is a couple little differences to them.Now the lid on the Pollack has a legend to tell you what circuit does what inside the connector, which is kind of neat, although our Hopkins one doesn't have that, but I think it looks a little bit sleeker. They both have spring loaded lids. And they're both designed to keep out dust and moisture, of course. But our Pollack has a slot and a slightly angled design, to allow for drainage if any moisture gets in there.A quick review from Elwood say, "It seems to be of good quality. Purchased to replace the OEM plug that had rusted after nine years." I think you got your mileage out of that one. This is a good replacement. And that'll finish it for Hopkins Endurance twist mount 7-way RV trailer connector, part number HM40930.
