This eliminates yelling "Hey, is it working?" at another person. It allows you to troubleshoot without help (Is it the trailer's lights that are bad? Is it the car's wires, etc...). Just snake the wire so you can see it through one of the driver side mirrors. 18936

Was able to verify, by myself, that wiring was correct and operational. Only bought it for testing, probably won't use it as a cover.16144

Simple but useful. Makes it easy for one person to test a harness. Reduces the guesswork when tracing trailer harness electrical problems.15316

This little gadget is worth more than the few dollars they are charging. Suspected my old harness wasn't working properly and this proved the theory. Am keeping for future usage. Def recommend this product for anybody with a 4-flat wiring harness. May not need it today but use it once and it pays for itself.15311

Just what I needed Living and having a hitch that is in and out of salt water you need this. Although I have not installed the products that I ordered they are upon inspection out of the box of high quality. I would like to say that this etrailor.com web site and their delivery process is phenomenal. It was delivered promptly and I was kept informed of the order and where it was in the process. Keep up the great job and I will return when looking for item you carry. Thank you.5743

Great little helper. I love this little item. It makes checking the function of my wiring simple. I use it as the full-time cover for my flat four-pole connector. I wonder if anyone driving behind me ever notices the tiny LEDs at night.3534

Peace of mind This is a very inexpensive way to make sure that everything is working correctly before you hook up to the trailer and keeps the dust out too.1380

I like it and it confirmed immediately that the wiring kit worked - Iuse this as the cap (did not cut the connected cap off the plug - just positioned it behind the plug so it doesn't show)23967
