Hello everybody. This is Jeff at etrailer.com. Today we're gonna take a look at this Optronics 20 foot long Wishbone 4-Way Trailer Wiring Harness. Now this 4-way trailer wiring harness will install on your trailer and connects to your tow vehicle to control your trailer light functions. This one we call a wishbone-style harness 'cause it's designed to have two brown taillight wires, one for each side of the trailer, that'll split for simple wiring of your trailer. This will allow you to run wires separately down each side of the trailer to your taillights without needing a jumper wire.
If you notice the ground wire on this with the eyelid on it, is the white wire that has 30 inch length to it. We mentioned the total wire harness length is 20 feet, and the wires are color coded, so that'll help with installation. We mentioned the white is your ground. The brown, there's two of 'em, one for each side, those are your tail lights, and then you'll notice the brown right here. If we do the brown and the yellow side, that's for your driver's-side stop and turn, and this one here is the brown and the green wire, which is your passenger-side stop and turn.
So you just run those down each side, driver's side and passenger side, and you don't have to run a jumper wire in between. But that should do it for the review on the Optronics 20 foot long Wishbone 4-Way Trailer Wiring Harness.

Just what I needed for my home-built bike carrier. My wife rides an e-tricycle and by the time I loaded the trike and a couple of bikes on this platform, you could not see the car's taillights or blinkers. This harness worked perfectly!
Wiring worked perfect for my project. I replaced the wiring on my 14 foot utility trailer. If I was to do it again I would buy the next length up. I would have liked to have a little extra wiring if I was to ever need it.
Plenty long for my trailer.
Harness is made well. Installation was vey easy.
It's a simple item but try to find it somewhere else as a stand alone product.
I've used etrailer before with great results and this was no exception. Let's be honest, if you've been to the site once, you're coming back!
I have a 5 x 12 utility trailer that has good lights but the wiring was a disaster. The harness connector had been patched and there were at least 5 splices throughout the lines. It was nice to lay out the new harness, make the light connections, tack everything up and out of harms way (there's an idea) and my lights work like new. I like the ground fastens under the jack bolt. Saves drilling a screw in (see the baby hole?) Good to feel safe on the road again. As easy and inexpensive as it was, I don't know why I waited so long.
Worked perfectly with the trailer light s.
Your sales staff is second to none. Keep up the good work. You shipped minutes after I placed my order!
Very impressed!

After trying to spice wires with other kits I found ETRAILER made a order got in just a couple days and had it wired hassle free this is a great product and I even order another one for my boat trailer and a easy plug kit for my jeep!! Will continue to use ETRAILER in the future!!
Quality harness. Not the cheap HF low quality wiring..
Great service and one of the only spots I can find the wishbone style plug!
Exactly what I thought when I ordered the product
Also excellent service
Fast deliver and what I order.
Just rewired a cargo trailer I bought that the lights were always going out. Found 20 butt connectors the guy used no wonder they worked off & on. Now with two new tail lights & new wiring with a straight connection everything works like it should. Everything I have bought from etrailer has been good quality & fast shipping.
Thanks
Cheap--wired it in to my Chevy and tried to separate the male connector from the female and the rubber sleeve separated from the terminals on the make connector. Threw the GARBAGE into the garbage and re-installed my old one. Do not buy this cheap junk. Wish I would have taken a photo.
Worked out very well and no issues a year later.
Some men, when they arrive at sixty five or above, run out and buy a fancy red sports car. I bought an old trailer that looked good and sturdy. It was very inexpensive. It needed some welding and rewiring. Luckily I have a neighbor who is an excellent welder, and the wiring was easy to find on the web and easy to install. I have gotten great pleasure using my trailer. I even thought about painting it red, but then that would look ridiculous.
Good thank you
Just wanted to let you know that the Optronics Miro-Flex Trailer Lights are working great!! Much brighter and more visible that the basic lights I replaced! Hope your business is doing well through this Covid crisis!! Thanks for the communication.

Outstanding
Fantastic !!!! Great product, exactly as detailed, exactly as pictured, easy ordering, and on time shipment / arrival. I have never wired a trailer before, but after watching the online video program and following the steps I was able to complete the project in a hour for a 14' boat trailer. Prior to ordering, I did a lot of price comparisons in my area and I could not beat etrailer pricing. Great product.

Thanks for the follow up - One year later the products are working spectacular and I keep plugging away at your company - telling all of my friends about it.
Exactly what I needed to begin rewiring a trailer. My sons cattle ate the trailer plug and pulled out the wiring in the tongue.

No problems! I installed in on my brother-in-laws work van and he hasnt complained.
Harness was purchased to rewire my Shoreland'r boat trailer. It came very well
packaged. The internal wire was strong and did not fray when stripping off the sheath. The main thing I liked was that the right and left (gr/br & yel/br) wires were separated all the way to the connector. The shipping fees were very reasonable. I would recommend this product all day. THANKS etrailer.com. Now if I could just figure out why I keep blowing my running lite fuse in my truck???

First you want to make sure your ground wires on your vehicle wiring and your trailer wiring are attached to bare corrosion free metal. If your grounds are properly attached, It sounds like you have a short circuit somewhere. You need to determine where the short is. To determine where the short is you need to test the vehicle side wiring and the trailer side wiring with a 12v probe-style circuit tester. I have attached a link below to help you.

great products and pricing with a fast delivery time. Thanks
What do y'all want a follow up to? If i had a nickel for every item I've ordered off of ETrailer, I wouldn't have to work for a few months... I keep coming back because the prices are fair, shipping is free and fast, and ETrailer has everything I need.
I do wish you sold trailer kits though. Being a welder, I have built a few trailers in my free time and sold them for a small side business. Why isn't there an axle, fender, brakes, springs (shackles and all hardware) tires and wheels kit? It would be nice to not have to go and click and add to cart all the multitude of items I need to build a trailer individually. Just saying...
Simple and quality wire harness set
Needed to rewire a friends trailer w/ an updated set up
Easy to use and install for this type of set up
