5 wire servo?

I have a steering servo out of a RC car it has 5 wires red, black , yellow, white and brown anyone know how to use these ?

A guess would be red and black are motor power and the other three are the feedback pot connections. Easy enough to confirm with a DMM. A photo might help.

Servos with 5 wires instead of 3 are basically 'circuit-less' servos. They don't have any of the circuitry inside of them. Instead, the 2 extra wires connect to (presumably) a receiver which has the servo's electronics on it.
Hope that helps!

Yes it's a racing RC car I'm trying to hack to add control through xbee and an Arduino micro as controller
