need a complete guranteed working power antenna assembly including the little yellow box


what i really need is just the control box from it its the yellow box that controls the height of the antenna for my power motor does send the antenna up but it looks like the control box took a dump

 

where is the yellow box located? is it right under the antenna? my friend took his working antenna out to replace it with the shorty antenna... hes not sure if he took out the yellow box

 

There's a screw at the top where it meets the sheet metal , just move it counter clockwise. I think there's one more screw inside the trunk. So simple.
