How do you fool a vehicle in to thinking it has a trailer with electric brakes attached? Answered
I am working on a vehicle and trailer testing box. I would like to have a circuit built in to it that makes a truck think there is a trailer attached and will send out voltage on the wire for the electric brakes. This is so I can have a volt meter measuring how much voltage the truck is sending and make sure it is linear. Would hooking up two 6ohm load resistors in parallel to the blue (brake) and white (ground) wires off of a pigtail plugged in to the 7way plug on the truck make it think there is a trailer connected and therefor send voltage, or does the truck sense a trailer hook up a different way?
