    New Build ESC Wiring Question

    Doing a scratch build and I have a ESC wiring question. The ESC had three wires coming out. I know which one goes to the receiver, but what are the other two for? The short red one is missing the connector and the manual says is it is for the voltage sensor. What plugs into this? I will be using the plug and play voltage sensor with the telemetry expander. Also what is the longer black/red wire for? The manual doesn't show this wire? Thanks for any help you can offer!

    Thanks but I've Googled and looked at this diagram a hundred times. It doesn't show three wires coming out. It has the ESC wire and the voltage sensor wire. What's the third in my picture? Also, I'm using the auto detect voltage sensor, so where does that plug into. Here is the sensor:

    The sensor instructions show it going directly into the Receiver which begs the question, what do I use the small red wire for on the ESC?

    Figured out the longer wire. It's the fan! Now just to figure out how the voltage sensor works with the plug and play sensors.

    You've gotta get that plug extension for the esc battery connection

    Can you elaborate? I'm not hooking to voltage sensor up to the battery but to the ESC.
