stepper motor? listed on wiring diagram but not index?
 

I dont see this part. I have the 6 pin connector in the body harness, I am stripping every non essential part and running the wires through the frame rails. So I need to know what it is to know if I need to extend it. I searched the posts, I read the manual but it is listed in wiring diagram as "stepper motor" and I cant find it in the index or anywhere else. the plug is near the main underhood fuse block. Any help appreciated.

correction "stepping motor"
