Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located beneath your vehicle, along the driver's-side frame rail.
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.

I'm a big fan of etrailer because of their service, their inventory and their delivery. I have three trailers, which like cars need maintenance. When I need a light, a spring, a wiring harness, or something rare I dint even bother looking local anymore. Local never has what I want anyway. This order was for an odd part - a connector that will hook lights off of my 70 Chevy PU harness. Rare, nobody carries it.... a special order that came in a month early. Thx!

1975 ChevroletC/K Series Pickup
I did receive these items yesterday and found them to be just what I needed and can work with for my 1975 Chevy Silverado c30 1t pickup. I needed not just one but two as this is my father's pickup and became my inheritance. On this pickup the whole wiring harness needed work and is now in the process of being completely replaced.
I needed two of these units due to the fact that it is hooked up to a 5th. wheel trailer so it is needing one to wire up the 5th wheel harness to the side of the bed and the other for the tow hitch assembly.
Yes I am a disabled veteran in lieu of my having back and head injuries while having served as a construction mechanic in the U.S. Navy Seabee's but I'm still a mechanic. I would like to thank you for having this product but however I just wished that there was one made for going from a 4 wire to a 7 wire T-connector but with the T-connector that allows for the adaption of allowing for the 7 wires to tow to come in from the bulkhead of the pickup and for the one outlet to allow for either one to have one set of wires for the 5th wheel hook-up or one to have one set of wires that allows for both that of the bumper along with those for the 5th wheel hook-up going to the interior side of the bed and with the third part of the T-Connector to allow for just the tail lights on these older trucks.

1976 Chevy C10
AWESOME!!! I went to Advance Auto, Autozone, Pep Boys, O'Reilly's and Napa looking for an adapter for my 1976 Chevy C10 Full Size Pickup and flatbed trailer and was out of luck. (In NY and TN.) Ended up with a ticket for no trailer lights. (Prior to learning about bicycle stickon battery operated lights.) Saw your awesome videos on You Tube, helpful pdf files, and product images which made me confident that this was the part I needed. THANK YOU SO MUCH FOR CARRYING THIS!!! Your website and links have been truly helpful in so many ways. This was a super easy hookup and anyone non-mechanical can do it. Came fast through UPS Standard, well-packaged, worked right away. I am super pleased. We got a lot of old pickups running around in Tennessee and I'll be sure to recommend this website to anyone in need!

1982 Chevrolet Blazer
Nice product, but unfortunately does not work correctly on Military Blazers like my M1009 CUCV. The right turn and brake signals did not work due to the way the original military trailer wiring was done. I had to splice into the military trailer wiring and now this is just doing nothing. Guess i will have to take it back out at some time. It does look to be a decent product for traditional civilian Chevy products.
by: Anthony Booher02/21/2016
Super easy install, but the female end of your inline adapter didn't fit as well as the original factory. I didn't have a working turn signal on my pick up after the install. I wiggled the adapter and the turn signal started working. I pushed it in as hard as I could and taped it in place. All is well for now, but you may want to tweak the fit of your adapter. I also purchased a 4 pin to 7 pin adapter. It worked great.
by: Craig Fitzgerald01/05/2015
I was dreading having to splice into the taillight harness until the folks at eTrailer recommended this wiring harness. Took five minutes to install and works perfectly.
by: Frank K.03/26/2015
Had one for my 1978 pickup sold the truck and now own a 1976 pickup had to have another harness to put in. It is easy to do and takes all the headaches out of putting in a splice in harness. If I sell this truck and get another any year I will buy again from etrailer for a plug in and play harness. Thank You Frank!

This product worked EXACTLY as it should. Easily plugged into connectors and worked perfectly. I used LARGE tie straps to hold all connections together just to be sure they don't pull apart, as my truck is used for off-roading as well.

Fast shipping ,good service
by: Earl 11/27/2021
The wire harness was super easy to install and works perfectly. The only thing you might mention in your instructions is the potential need to replace the original flasher module with a heavy duty one. The trailer signals were weak and blinked rapidly. it took me a bit to figure out the need for the new flasher but once I did everything works fine!

- 4-Way Trailer Wiring Harness Recommendation for 1984 Chevy C10For trailer wiring for your 1984 Chevy C10 for just the trailer lighting you'd want the part # 118311 which covers all of the trailer lighting functions.
view full answer... - Factory Connection Point for Trailer Wiring on a 1984 Chevy BlazerAs far as I could find the connection point on the 1984 Chevy Blazer is located along the driver side frame rail near the back of the vehicle (see instructions link). You may be able to pull it down from in front of the gas tank or up and over the frame rail. Otherwise, the way that you have described it, sounds like you would have to lower the gas tank to reach the factory connection point.

- T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector 1983 Chevrolet S10I would agree that the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118311 looks to be a match, however this product is not guaranteed to fit your 1982-1984 Chevrolet S10 Pickup. There is a possibility that it may work but our installation and test fit experts have not verified that particular vehicle. We do carry an alternative by Tekonsha # 18252. This is a universal fit, plug and lead style hardwire kit. It also includes a circuit tester, and 4 quick splice connectors.
