Hopkins Custom Fit Vehicle Wiring - 33355

    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing
    • Locate connection points behind rear bumper
    • Plug in connector

  • Protective connection terminals resist corrosion
  • Comes with dust cap for 4-way flat connector, cable ties, and terminal grease packet for electrical connections


Specs:

  • Maximum amperage:
    • Turn lights: 2.1 amps per circuit
  • Wire gauge: 16
  • 90-Day limited warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind your rear bumper, on the driver's side and passenger's side.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Tail Light Converter

A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 33355 Review

Today we're going to review part number 33355. This is the Hopkins Plug and Tow Vehicle Wiring Harness with the four way flat trailer connector. This is a custom fit part. It is designed to fit the 1993 - 1998 Toyota T100 pickups and also the Toyota Tacoma starting in 2005. Now because it's a custom fit part, I always like to recommend to go to our website, use our fifth guide .. put in your year, model, make vehicle and it'll tell you if this will work for your application. Now each vehicle's specific connector right here is pre-wired.

Uses original OEM connectors to give you a water tight protection. Guaranteed fit and a nice look. There is not cutting or taping of the wires. They use a sixteen gauge wire. The four way trailer connector right here includes this nice handy dust cap.

So when your not connected to a trailer, you can just put your dust cap over your four way just like that. And when you do that it will protect those terminals from any damage or from the elements themselves. They do include some easy to follow instructions. And each kit will include everything you need to complete a full wire flat installation. They even give you some dielectric grease to be able to put on all your electrical connections to keep any corrosion from appearing. And they give you a couple of cable ties that take up any slack in the wiring.

The converter that this uses is a powered converter. Has circuit protection. Which is included in a weather proof, double molded design. And that circuit protection with guard the tow vehicle and the converter itself from any shorts in the trailer. The maximum amperage load on this harness is 2.1 amps on the left turn and 2.1 amps on the right turn. The basic way you go to install this is you go to the back of the vehicle and underneath the rear bumper on each side .. you'll find some connectors that these will connect into.

And if you'll notice, a good idea is the yellow wire is for the driver's side and in this case they actually put labels on the connectors to help you out. But a good thing to remember is the yellow is for the driver's side. So you just connect these to the two connectors on that side. Passenger side again is labeled. But the good thing to remember is the green wire is the passenger side. So you make your connections there. And then what you want to do is use these cable ties to attach your converter down so it doesn't bounce around. Run your length of wire out the back to be able to connect to your trailer. And as I said anytime you make your electrical connections you probably want to put a little dielectric grease on them to help prevent any corrosion. But that should do it for the review on party number 33355 the Hopkins Plug and Tow Vehicle Wiring Harness with the four way flat trailer connector.

Really easy to install. Just one thing... All of the wires in the harness are well wrapped and protected except one green wire that runs the full width of the vehicle. I went to NAPA and got some spiral wrap to protect it. Other than that, it works great. Took me 30 minutes to install, not counting the spiral wrap. 291980

I just installed on my truck, it took me about 20 minutes. very professional product. looks like factory install minus the wiring loom, however it does have fiber wrap where it matters which is an important detail. now I don't have to worry about shorts in my wiring since you don't have to slice and splice, which ain't so nice. My only regret is that I didn't include in my order a mounting bracket which is $3-$5 which would have really buttoned up the project nicely. (this should be a suggested purchase when ordering these kits). As far as e-trailer... I got the product FAST! No Damage! Everything included! 2THUMBS UP. The only improvement I could suggest is 4 more zip ties included. you wouldn't need anything else. 392149

Ask the Experts about this Hopkins Custom Fit Vehicle Wiring

Do you have a question about this Custom Fit Vehicle Wiring?


  • Does Hopkins Trailer Wiring Harness 33355 Fit a 2016 Toyota Tacoma
  • I have a trailer wiring solution for your 2016 Toyota Tacoma, but the Hopkins no longer is listed for Tacomas newer than 2008. You instead would want the Curt harness part # C56282.

  • Upgrading Toyota Tacoma from 4-way Flat to 7-way Round Trailer Connector
  • Sounds like you are looking for a 7-way for a brake controller and a 12v hot lead for your 2008 Toyota Tacoma, so I would recommend the Universal Installation Kit for Trailer Brake Controller, part # ETBC7. This includes everything needed to install the wiring for the 7-way connector, once you have the 4-Way installed. I have included a couple of videos of part # ETBC7 for you to check out. Although we offer many different brake controllers, I would recommend a proportional-type controller...

  • Trailer Wiring Harness for a 2016 Toyota Tacoma SR5
  • The trailer wiring harness options for the 2016 Toyota Tacoma right now are all hardwire installations, since the truck is still a very new model, so that excludes # 33355. But you can use the ZCI harness # 119250KIT to avoid having to cut and splice into the vehicle tail light wiring.

  • What Would I Need to Wire a Prodigy Brake Controller # 90185 to my 2005 Toyota Tacoma Prerunner
  • The connector you found could be the brake controller wiring harness If your 2005 Toyota Tacoma Prerunner has the factory tow package. If so, then you will have to use the Toyota connector that should have came in your vehicles glove box to connect from your Prodigy Brake Controller - Proportional, part # 90185, to your 2005 Toyota Tacoma Prerunner. If you are missing this connector you will need to go to a Toyota dealership to track one down. I would also recommend having them look at...

  • Wiring Adapter for Boat Trailer With 5 Flat Plug
  • There is a solution for you to use both your 4-way and 5-way connectors on your 2007 Toyota Tacoma though it is not a quick plug-in option. Instead, you would need to use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036 which will change the 4 flat on your Tacoma to a 5 flat, though you would still be able to use the 4-way on your trailer by simply plugging it into the 5-way. I've added a link to a video review as well as a link to a video install for you to take a look at.

  • Recommended Wiring Harness for 2008 Toyota Tacoma to Connect to Boat Trailer
  • It sounds like you are needing a 4-Way or 5-Way flat connector on your 2008 Toyota Tacoma to connect with your boat trailer. If you do not yet have any connector installed, I recommend the Hopkins Plug-In Simple Wiring Harness # 33355. This custom harness will plug into factory ports located behind the rear bumper (on the driver and passenger side). This will provide you with a 4-Way flat connector. If your boat trailer is equipped with a 5-Way connector, then you can simply add...
