I have a steering servo salvaged from a radio controlled car. It has 6 wires, 3 more than a conventional servo. Can anyone tell me what the extra wires are for?

Stepper motor??

It is based on a conventional d.c motor so I don't think it is a stepper.

In the cheap cars I've hacked the steering is not by a packaged servo, three of the wires are connected to a pot and the controller board takes care of the control. You could use it with an analogue pin and make your own servo.

I would go with James Carter on this one.
3 wires for the pot and 2 wires for the motor. The 6th wire is probably the motor casing. Alternatively, it may be an even more crude system that uses fixed positions from a rotary slide switch rather than a pot.
You should be able to work it out with a multimeter and carefully forcing the output to move by hand.

Chances are that if its something Japanese like from a Tamiya or Nikko model then its an analogue servo like the guys said. If its German like a Dickie model, then you might have a digital servo with a gray encoder shaft. Ive seen those on some cheap german rc cars before.

James Carter has correctly identified the wiring. Thank you all for your help.
