## Description

CURT electrical connector brackets provide a simple solution for mounting wiring to your trailer hitch on the rear of your vehicle. Connector wires can be a nuisance when they are just lying around. They can get tangled up with cargo and even damaged. An electrical connector left to hang off the back end of your vehicle is an even greater hazard. Secure, protect and optimize the use of your electrical connector by mounting it with a CURT connector bracket. This trailer wire connector bracket is designed to hold a 4-way flat socket. It features sturdy steel construction with a black finish and can be mounted on your vehicle or trailer hitch. When it comes to plugging in your trailer lights, it pays not to skimp out. CURT electrical is the smart way to ensure that your trailer lights and electrical systems are prepared for the road ahead. Keep the power flowing, no matter where your adventures take you, with quality electrical products from CURT.

Review: This installed nicely. Had to pick up a couple of stainless steel bolts. The harness connector was a bit tight and hard to get in but once through really solid. Cleaned up the harness install nicely. Good quality unit.
Review: I bought a CURT wiring harnes for my jeep, but a different brand hitch. The hitch came with a clip for the 4 pin, but it was way to big for the curt harness. Combine that with my hatred of dangling wires and well... I was going a little nuts. This is shiny black and my hitch is powder coated (looks like bed liner finish); however, it slipped right behind the clip that was too large. The wife held it centered while I buzzed in a couple of self tappers and TA-DA!! Okay, it does hang about a half in below the the other clip, but if you are up under my jeep and notice that, you got bigger problems. The 4 pin snapped in and felt pretty tight, it should work just fine. It does not come with mounting screws, I assume that's because every vehicle is a little different or maybe their hitch does and I'm not aware, but it installed easy for me.

## Questions & Answers

**Q: Will this work with a curt 13392 receiver hitch**
A: They pretty much work for any of the flat plugs.  Not sure what the wiring harness looks like on the 13392 but you will need to add the screws for wherever you want to place it.

**Q: I can not get the wiring harness into the bracket does it need to be pounded in or trimmed?**
A: There are several wiring harness connectors that are found on both the male and female ends of the connector.  I would take the bracket to like a West marine or some other place where you can have hands on the connector and find the one that fits and rewire your harness to make that one work.  Good luck-M

**Q: Will this work with the Draw-tite 75782 hitch?**
A: If your hitch has a mounting flange and the center to center distance on the holes matches, yes it will fit. Some hitches do not have a place to mount a plate, in that case you'd have to mount it to the vehicle. Many Draw-Tite models have a mounting flange.

**Q: Why weren't the mounting screws included???**
A: I bought 2 of these (neither fit either of my Jeeps light plugs without modification).  One came with screws, around $6.50 or so.  The other had NO screws for $4.85.  Different vendors.  You get what you are looking at, and in all BUT ONE of my previous experiences, Amazon vendors are pretty good and Amazon very supportive .
