I recently got a new toy in. It has a cooling fan on it to keep the elecs cool but in 40* weather I don't have that issue running 40mph. So my question is how do I get it so that I can turn it off and on by the 3rd channel on the radio? Here is a pic to show you guys the set up.

I know it is a dumb ass noob question but I cannot seem to make it work like I want. I did do a search and didnt see what I was looking for.

An here is the truck. YEAH ITS UGLY BUT SO WHAT ITS A FORD!!!!!!!!!!!!!!

A channel by itself won't actually switch anything. The 3 wires which plug into a reciever (for any channel) provides power, ground, and a control signal to tell a servo or ESC what to do. An adapter such as the one in the link above takes the control signal and is capable of turning on/off a switch which you would use to turn your fan on/off (or lights, etc...).

Anyone know if there is a Radio Shack type version out there, or how to make a homemade switch? I was hoping to get this project done this weekend and dont want to wait to order online and have it shipped

Yes call me impatient...

Quick/easy answer.......?
I say get a small servo to plug into an empty receiver port. Use that to trip a small micro switch to turn/off the power to the fan. The fan power would have one wire/leg run through the switch and the servo would open/close the switch as directed by the transmitter.
