assign wheel collider through script

i have an object called wheelColliderFl which contains a wheel collider, i know i can drag and drop this object onto a script , but this is a bit messy for each time.

is there a way so that i can get the main game object to do , find("wheelColliderFl );

i tryed this but it not seam to work

I hope this answers your question: (written for C#, since there was no language specification)

GameObject _temp;
_temp = GameObject.Find("wheelColliderFl");
_temp.AddComponent("YourScriptHere");

If you are just trying to gather these objects inside your script all you need to use is this line:

GameObject WheelCollider1 = GameObject.Find("wheelCollider1");

Now you can Assign any of those objects wheel colliders:

   WheelCollider1.AddComponent<WheelCollider>();

(It will require a rigid body)
