Hopkins Towing Solutions 47185 Multi-Tow 4 Flat to 7 Blade and 4 Flat Adapter

The hardest part is found the wiring diagram for LR3 but it work, just follow booth diagrams and its gonna take around 25 min.

Installed very easily onto my existing 4-pole connector on my 1997 GMC pickup. Found a good lip under the bumper to bolt my bracket to, and made my own ground on the frame for the ground wire. Havent actually hooked it up yet, but a multi-meter shows 12V power in the correct spots when various vehicle functions occur: blinker, tails, brakes, etc.

Ive wired in a lot on a lot of cars the 7way is awesome for your camper and the 4 flat is nice to rent or if you have both stile trailers like me just back up plug in and hook up and go other then trying to find you 7 to 4 adapter you let a friend use so you got to buy anather and always use dielectricel grease on the wires and plugs and you will never have a problem with the ends by the way those 7 way to 4 flat adapters burn out this plug if kept up will last the life of a car

On my particular car, there was no easy, inconspicuous, place to mount the bracket for this adaptor so I had to get inventive and make a special bracket to attach it to the car. Again, thats a design flaw of my car, not the unit itself which otherwise is excellent and works beautifully.

I have purchased several of these little guys for the purpose of installing them on all of my tow-capable vehicles. They work great, and do include all of the necessary hardware and bracketry to mount onto a vehicle. I wish they came with heat shrink butt connectors, but my guess is that request would drive the price up. All of the contact surfaces were clean and corrosion free. The rear of the round connector appears to be water tight and durable. The copper wiring meets all of the AWG specs for the application it is designed for. I did use this in conjunction with a

Received the Hopkins 47185 kit on time and in factory packaging. Nice that has both the 4 Pin and the 7 Pin Flat connectors. Just mounted the bracket and then place the connector unit into it with the supplied screws. The crimp connectors were already on each of the wires, so just matched the colors to the factory wires and crimped them on. Works great, put a little bit of grease on each pin and taped over each wire to seal moisture out.

Bought a trailer with brakes about a year ago, but only had the 4pin trailer plug (no tow package) on my F150. Bought this piece, got it in 2 days with Amazon Prime, and installed it the same day I got it. Install took about 30 minutes (you could do it faster if youre familiar with the wiring), but overall pretty easy. 4pin plugs into the new 4pin (plug and play), splice blue wire for the actual brake controller, splice black for power, and white for ground (to metal of vehicle) -all not difficult (youtubed this video for help: http://www.youtube.com/watch?v=XWq9Fwj1D-8). Now I have braking power on my trailer (also got Curt 51110 Venturer Brake Controller and adapter for simple installation: 5min), all for almost $80 and about 45min of install time. Took trailer for a short trip and everything works great, next is 1600miles, so Ill update if something craps out. Otherwise, consider everything great.

I had it for 4months now and no complaints it helps when I hook up trailer.

The ground pin on the 4-wire plug broke off even though its never been used. I installed this on my Ford van without too much trouble. I was able to get an adapter to plug right into the vans OEM trailer wire harness at the back of the van and plug the other end into the back of this adapter. I have to run the brake, 12V accessory and reverse light wires separately only because my van doesnt have those wires built into the tow package harness. The real downside to this adapter is the cheap manner in which it was made. The actual wiring side is fine. The plug itself is the issue. Its just really cheap and fimsy. The 4-wire connector broke off just by me removing the plastic cap a few times to test the wiring.

Did not come with any instructions had to look it up online to figure out what wire went where
