I got a new receiver for my truck and it works great, however, it came with an extra part that I wonder if I should be using somehow.
It looks like a little wire loop on a plug. Am I supposed to plug that in somewhere?
that is called a bind plug.
its used only when you want to "bind" a receiver to the radio.(its how you make the 2 talk to eachother)
if you get other recievers, you can bind them to the same radio.
there are vids on youtube(and i think redcat's how to vids) showing how to bind them.
