Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM40615 Review


Hello everybody, this is Jeff at etrailer.com. Today I'm gonna take a look at this Hopkins plug-in vehicle wiring harness with the four-way flat trailer connector. Now this is a custom fit part. It is designed to fit the 1999 to 2002 Ford Windstar vehicles and also the 2003 Ford Windstar, as long as it's built before November of 2002. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle and it'll show if this will work for your application. Now this will provide a four-way flat trailer connector at the back of your vehicle to power your trailer's signal lights.

It is compatible with five-pole, six-pole, and seven-pole adapters that we do sell separately on our website. And this harness does connect very quickly and easily. All you have to do is locate your connection points, which will be behind the taillights, plug in these connectors, one on each side, one on the driver's, one on the passenger side, and then run your power wire to your vehicle's battery. Now this does include this circuit-protected taillight converter. This black box here and this is to ensure that your vehicle's wiring will match that of your trailer, provides protection against electrical shorts and overloads.

And it is a powered module. That's why you'll connect it directly to the battery to avoid overloading your vehicle's electrical system. This does also come with this dust cover for your four-way flat connector right here. Basically what you'll do with that is just go ahead and install that onto your four-way, and you can leave it on there, you don't have to remove it once you get it installed, just use that whenever you're not plugged into your trailer. you just go ahead and put it on to the connectors, that cap will cover those, and protect 'em from any damage or from the elements.

Also comes with everything shown here on the table. Comes with some cable ties, some terminal grease to put on your connections, grounding screw, a fuse, inlet fuse holder, and some extra wire. And I just wanna describe how this all goes together briefly, but what you'll do is, it comes with a good set of instructions that'll describe where all your connection points are. But what you'll do is go to the rear of the car, gain access to behind the taillights, and then take your connectors here that have the yellow wire in it, that's for the driver's side. You'll go ahead and plug that in behind the taillights.

And then you'll take the T-connectors with the green wire in it, that's for the passenger side. You'll run that over to the passenger side. And this box does have some weight to it, so you do wanna attach this to a nice flat surface if you can. Does have holes in it that you put screws through there or you can use double-face tape if you need to, run this out towards the back toward your trailer would be. And then there's two remaining connections to be made. This white wire has the eyelet on it that needs to connect to a good clean ground. And as we mentioned, if there's a ground nearby, you can use it, if not, they do offer a grounding screw to make your own ground. And then this red wire with the butt connector on it, this'll need to run to the vehicle's battery at the front of the car. So they do give you some length of wire to do that. So you'll connect the length of wire in to this butt connector, run this other one up to the front. And you don't want to connect it directly to the battery. You do want to go through this in-line fuse holder. So you'll connect it to the butt connector on this side and then the size, it'll connect to your battery. And then it includes a 15 amp fuse already in there, so then it'll be fuse protected. And as we mentioned, this package of terminal grease will go on all your connections when you make them. And then you'll have some extra cable ties that take up any slack in the wiring. But that should do it for the review on the Hopkins plug-in vehicle wiring harness with the four-way flat trailer connector.
