  • Connects quickly and easily - no cutting or splicing of wires

    • Plug in T-connector

Installation

This custom-fit T-One connector plugs into your Chevrolet Express Van's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your cargo area. You will need to remove the trim panels to access this harness.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your cargo area.


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-One 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 Chevrolet Express Van's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light 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 Chevrolet Express Van operate.

Video Transcript for Tow Ready Custom Fit Vehicle Wiring 118377 Review

Today we're going to be taking a look at a T-One vehicle wiring harness with a 4-pole flat trailer connector. This product is going to fit the 2000 to 2002 Chevrolet Express van and GMC Savana. It's going to provide a 4-way flat connector at the back of the vehicle to power your trailer signal lights. This is compatible with 5-pole, 6-pole, and 7-pole adapters. The adapters are sold separately, and it's going to come with a dust cap for the connector. That way you can cover up those connection points when your plug's not being used. It's also going to include a tail light converter.

This is going to ensure that your vehicle's wiring matches that of your trailers. The unit is going to connect quickly and easily. You don't have to worry about cutting or splicing any wires. All you have to do is look at the connection points in the rear cargo area, and then you can see here that you're going to have two sets of connectors. One set goes to each side of the vehicle.

These plugs are going to match up perfectly with the ports on the vehicle, and they're going to snap lock together for a secure fit. It's also going to come with two brand new locking tabs for further security, making sure that the tabs are fully in place and seated together. These are to be used along with the existing tabs on your vehicle, but it does come with two brand new locking tab provided with the kit. Once you have that connected, you'll need to mount the converter. You can use the double-sided adhesive tape provided with the kit, you could use one of the screws, or you could use the large zip tie to get it secured. Once your installation is complete, the 4-way connectors are going to be stowed in an out of the way location within your cargo area. That way, you can just pull it out the back of the vehicle whenever you're ready to use it, and then you can roll it back up, stow it away when it's not being used, and so you're ready to use it next time. It's going to come with your detailed installation instructions. These are going to help walk you through the entire process step-by-step, and it's also recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle and the 4-pole connector itself, and that's going to help prevent corrosion to the connection points.

If you need some of that, you can find it right here at Etrailer.com. It is sold separately. That's going to do it for today's look at the T1 vehicle wiring harness with the 4-pole flat trailer connector.

After spending a week looking at couple auto part stores a trailer connector for may work van 2001 GMC Savana, no one has it. One auto service told me that they need to check out wire by wire and take a time. Uhaul may do it but expensive. I jumped on Internet and found the T-One 118377 Wiring Harness from Etrailer.com, cost less than $40.00. It took me only 10 minutes to finish the job. I am really happy with Etrailer super fast service/shipment and very clear instruction. It is excellent place to shop when you need help. 15184

  • Adding a Trailer Brake Controller to a 2004 Chevy Express Van 3500
  • If your 2004 Chevy Express Van came with a factory installed 7-Way trailer connector then the blue output brake wire will already ran from the back to the front. It is located under the dash near the emergency brake pedal. It will connect to the broke controller blue wire. The white wire will go through the firewall and attach to the negative battery terminal. The black wire will go through the firewall, attach to a circuit breaker and then go from the circuit breaker to the positive...

  • Recommended Wiring Harness for a 2002 GMC Savana Van
  • There is definitely something that doesn't seem right here. What I recommend is the Tow Ready wiring harness part # 118377. It will definitely bypass the issues you are currently experiencing. This will provide the 4-Way connector to the back of your 2002 GMC Savana to power your trailer lights. This harness includes the T-one connector that combines the brake and turn signal functions on your 2002 GMC Savana. I highly recommend using dielectric grease to help prevent corrosion from...

  • Trailer Wiring Recommendations for a 2001 GMC Savana Van
  • You will want to go with the Tow Ready Custom Fit Vehicle Wiring # 118377 as it is designed to work on vehicles that do not have trailer wiring. The Replacement OEM Tow Package Wiring Harness # 118240 that you referenced is designed as a replacement harness for vehicles for that have a factory wiring harness. I attached an installation video for the Tow Ready Custom Fit Vehicle Wiring # 118377 that you referenced. Once installed if you need a 7-way trailer connector I would recommend...

  • Installing a 7-Way Connector in a 2000 Chevy Express Van
  • To hard wire your 2000 Chevy Express Van with a 7-Pole connection, first, you will need Tow Ready Custom Fit Vehicle Wiring, # 118377. I have included a link to the instructions below. Basically, you plug in this wiring harness into a taillight connection and run the wires where needed (to the other taillight and then to the rear of the vehicle). With that installed, you will then add Brake Controller 7 and 4 Way Installation Kit, # ETBC7, which will provide you with the 7 pole connection...

  • Trailer Wiring Harness for a 2001 GMC Savanna
  • I checked the owners manual online for a 2001 GMC Savanna Van and it does not list any tow package fuses in either the in-cab fuse panel or the one under the hood. You can double-check your owners manual to confirm. If your van did not come with a trailer connector then to add a 4-Way flat you would need # 118377. Then to add a 7-Way you would need # ETBC7. I have included some links that show and explain the ETBC7 installation for you.

  • Parts Needed to Install Hitch, Brake Controller, 7 Way and 4 Way on a 2002 Chevrolet Express Van
  • First we will start off with the hitch. I recommend going with the Curt Class III Receiver Hitch, # 13040, for your 2002 Chevrolet Express Van. This hitch receiver bolts directly to the frame of the van with no welding or drilling required. For a t-connector we have the T-One Wiring Harness, # 118377, that plugs directly into your existing taillight wiring without any cutting or splicing. In order to obtain a 7 way at the back of the van, you will need to install a Universal Installation...

  • How to Install a Brake Controller on a 2002 Chevy Express Van
  • We would be happy to explain how to install a brake controller like # 5100 or # 90885 on your 2002 Chevrolet Express Van but there isn't a pig tail that will fit your van. You will need to hardwire in the brake controller. If your van came with a factory 7-Way trailer connector the blue output brake wire already ran from the back to the front. It is located under the dash near the emergency brake pedal. But the other 3 brake controller wires will need to be hard wired in. The white...

  • Parts Needed to Install a 7-Way Trailer Connector and Brake Controller on a 2001 GMC Savana 2500
  • The brake controller and wiring options for a 2001 GMC Savana can be tricky. If you have a bundle of wires in the jack storage compartment, I would ask that you test them for function using a circuit tester like # 3808, and label them. If you find that you have 7 wires (left turn/brake, right turn/brake, running lights, 12 volt power, reverse lights, brake controller output, and ground) then you can use the Pollak 7- and 4-Pole Trailer Connector Socket, # HM40975 and Pigtail Wiring Harness,...

  • Can Tekonsha Prodigy P2 Brake Controller, # 90885, Mount On Lower Dash Slope On 2000 Chevy Express
  • Yes, you can mount the Tekonsha PRODIGY P2 Brake Controller, # 90885, on the slope of the lower dash. The Prodigy brake controller can be mounted from 0 degrees to 360 degrees vertically in the direction of travel. The front of the Prodigy has to be horizontal. The Tekonsha PRODIGY P2 Brake Controller, # 90885, will work for 2, 4, 6 and 8 brake systems. If you have the 7-wire Tow Package on your 2000 Chevy Express then you will use the Hopkins Adapter 4 Pole to 7 Pole and 4 Pole,...

  • 2002 GMC Savana 2500 Wiring
  • The wiring harness needed will depend on whether or not your Savana was equipped with the factory tow package. If you have the tow package, with the connector in the jack storage compartment, you'll need the part 118240, if not, you'll need part number 118377. Links to both of these parts are included below.

  • Recommended 4-way T-One Vehicle Wiring Harness and 7-way for 2000 Chevrolet Express Van
  • If your 2000 Chevy Express Van has the tow package then the 4-way wiring harness you will want is the # 118240. If you do not have the tow package then the # 118377 would be the correct 4-way wiring harness for you to get. To adapt these 4-ways to a 7-way plug, you will want the # ETBC7. If you don't already have a brake controller, I recommend the Tekonsha P3 # 90195, because of its easy user interface. The P3 is a proportional brake controller which means it senses how the tow...

The wiring kit you purchased, The Upgraded Circuit Protected Taillight Converter Hardwire Kit # 119178KIT, will fit your 2000 Chevrolet Express Van and is compatible with the Curt TriFlex Brake Controller # C51140.
