Quickly and easily install a 4-way trailer connector on your Ford F-100, F-150, F-250, F-350 with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.
Once installation is complete, the 4-way 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.

Today we're going to be taking look at part number C55301. This is the Curt T-connector vehicle wiring harness with a four pole flat trailer connector. This product is going to fit 1973 to 1979 Ford F100s, F150s, F250s and F350's. It's going to provide the four way flat trailer connector at the back of your vehicle to power your trailer's signal lights. The unit is compatible to 5,6 and 7 pole adapters. If you don't have those, those are available here on our website and those will be sold separately.
The benefit of this system is that it's going to connect quickly and easily. You don't have to worry cutting or splicing any of your wires. All you have to do is locate the connection point behind the rear bumper. Simply plug in this T connector right here, very simple, it just snaps right into place, then make your ground connection. The ground connection is going to be your white wire with the ring terminal attached to it.
Curt's going to include the self tapping screw to get that secured. Over here on the four way flat connector, it's going to come with a nice dust cap. That's going to protect the connection points when they're not being used. We're going to have about 36 inches of wiring from the back of one plug to the back of the other. The product is made in the USA. It's going to come with very detailed instructions.
It's going to walk you through the installation process step by step. It's going to come with some zip-ties, that way you can secure any excess or slack wiring that you may have. It will make for a pretty tidy appearance. Once installation is complete, the four way connectors going to be stowed beneath the trailer near the trailer hitch. We do recommend using a mounting bracket. That's going to be sold separately.
That's going to help keep the connector secure. We're also going to recommend that you use a small amount of di-electric grease on all your electrical connections. That's just gonna help prevent any corrosion from being able to settle into the connection points. That's going to do it for our review of part number C55301. This is a Curt T-connector vehicle wiring harness with a four pole flat trailer connector. .

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.I recently put a '77 F-100 cab and bed on a 2006 Crown Victoria LX Sport chassis and wanted to add a trailer hitch to it to pull my small utility trailer. Since there is no "Off the shelf" hitch for this setup I had to make my own. This connector is just what I needed to hook up the wiring for the trailer.
Just what I needed to make a seamless splice into the truck for my trailer plug. Quick delivery and a really nice tracking program. Thanks

It is still working and is as it should be. The main thing was the ease of installation.
This item fit perfectly. Just unplug the truck bed & insert the "T".
No new connectors or wire cuts & splicing. Telephone conversations were clear and helpful in selecting the part. The grounding instructions were very plain & easy to follow.

I have an old 75 Ford F250 & needed trailer lights. Your plug in wiring is perfect. Everybody else wanted to cut & splice my truck wires - this always ends up badly because of corrosion. Your plug-in is still working great and there was no wiring damage to the truck. I will recommend you to whoever asks & if I need anything for trailers, etc. you will be the first website I check. Thanks again for a perfect fit.
Delivered quickly. Good price.
After searching High/Low for a like-product at several local auto parts stores and continually coming up empty-handed, I then took my search efforts to the internet and quickly discovered that etrailer.com had exactly the item I had been searching for. Hooray and Thanks ... etrailer.com!
The T-connector I'd been searching for needed to fit a mid-70's Ford pickup which required a bumper-mount, 7-pole RV receptacle installed. With the advent of parts such as "Curt's T-Connector" ... installing RV plugs is now a painless, hassle-free operation. It's simply plug & play and will not cause damage to the existing wiring harness on your tow vehicle. It's simply the BEST way to ready your vehicle for RV towing.
The personalized service I received from etrailer.com during this sales transaction will keep me coming back as a customer. There is no better place to purchase such parts! Keep up the good work!

This product is a lot better way to get a trailer plug supply on your vehicle, no cutting and splicing your main wire supply, just unplug the master plug match the ends with this plug and join together. Worked perfect on my 1976 Ford F-250. No pictures. Sorry.
Plugged right in and able to wire my camper, yes - camper not trailer, with no alterations to the original wiring harness.
Bought this for on a 1977 Ford F 250, recieved product before the date it said it would be here. Product was recieved in good shape, quality of the product was good and fit like it was an OME. Would recommend this product and etrailers. Thanks etrailers great service and turn around time.
Product was better than advertised. The four wires were hard wired into the T connector which in my opinion eliminates future problems. Extremely happy with this product and will use this company for any future needs as applicable.
Part showed up quick and works perfect. Glad I didn’t have to splice into my wiring harness.
Fit Perfect...Makes 4 Wire Trailer Wiring A Snap !!
Inexpensive and handy.
Plug and play trailer lights.
Excellent product and perfect connection to my truck, no splicing wires or cutting at all, just plug and go.

Does what it should do, solid product.
Good product, easy to install, great website and quick delivery. Works fine , lasts a long time.
