I was given a switch harness and have no clue how to connect it. Here is a picture of what it looks like.

jsf135,
Ok, here's how you use the switch harness. Referring to you picture. The connector on the left will go into the the battery connector of your receiver. The upper right connector will connect to your battery. And the lower right connector is to connect a charger to when you are charging the battery.

Hope this helps.

You have two male ends and a female. One male goes to the receiver and the other is to charge the battery You can levae it hanging or install a little battery charger jack in the side as most do . The female goes to the battery itself.

You have a male connector on one side of the switch and a male and female connector on the other end of the switch.

The end with ONLY the male connector gets plugged into the receiver.

The end with the male AND female connector.
The female connector gets connected to the battery. The male connector is used for charging the battery and only works when the switch is in the off position. The connector for charging the battery can be left loose or can be mounted in a switch/charging jack connector.
This is what a switch/charging jack connector looks like:

This is a disassembled view showing all the parts. They are easy to assemble and do include instructions on how to do it. Personally, I like the convenience and neatness of the switch/charging jack connectors.

Here is a diagram from a Hitec manual.
The plugs on the receiver go from 1 on the bottom to 8 on the top.

Hope this helps
