Return window closed 7 days before the unit failed and will not output video signal to OLED tv.
Style: STR-AN1000 AV Receiver only
Avoid buying renewed. Learned my lesson so far. Unit stopped putting out video signal 7 days after return window closed. Now I am stuck with a very clunky and expensive audio box.

real time and energy saver, as well as $
Size: 16AWG Wiring Harness-2 Leads
If you have a set of LED lights that didn't come with a harness , you can't beat this for the price. By the time you figure in the cost of the parts ( wire, switch, crimps/connectors, not to mention a relay if you are using one) to hardwire a set of lights, let alone the time to assemble, this set up is cheaper by far. harness length is ample, you get a pair of pigtails with connectors for a pair of lights, the relay, switch, fuse block and fuse, and ring terminals for power all assembled for what a switch and some wire would cost. Made everything quick, cheap, and easy.

Great wiring harness for light installations.
Size: 16AWG Wiring Harness-2 Leads, Size: 16AWG Wiring Harness-2 Leads
This is a great wiring harness for LED lights. These come in one or two leads application. All that means is that they come ready for one or two lights, depending on your installation. The plug in connectors for each light comes with the set so that is a plus. I’ve attached a picture of the plug/connector for the lights so you can take a look at them. Although the relay is an “overkill” for low wattage LEDs, it’s OK to have it just in case you decide to change your lights for larger ones or halogens, in the future. In my case I will be using this harness in my motorcycle. It is very long for my need, which is great for cars, but too long for motorcycles since you have to remember that room/space is scarce in motorcycles. I ended up cutting the wires to my desired length and using heat shrink butt connectors and “glued” heat shrink covers for waterproofing the connection points. All in all these are great quality and I am very happy with them.

Wire length between the two connectors is short for a full-size pickup
Size: 16AWG Wiring Harness-2 Leads
I used the harness to wire ditch lights on opposite sides of a full-size pickup (F150). The wire between the 2 2-pin connectors was about 18 inches too short. Fortunately, splicing the wires from the (Nilight) ditch lights and the included pigtails gave barely enough length to reach the connectors. The connectors are buried inside the trim channel for the cowl; I'd have preferred they were exposed on each side to allow for easy swapping of the lights, but I can live with it. There is more than enough wire from the first connector to the relay for my all-under-hood installation, but I didn't think to measure if it would reach into the truck bed. The harness is of good quality and is a very good value. It would be a 5-star if it weren't for that little length issue.
