Single red wire on top of sending unit?
 

How does it attach? 85 swb gmc. Not the ground, it's a single wire and kinda looks like it has a little boot over where it attaches.

Some of the different manufactorers make them differently, yours may just have a male pin on the top that a female connection on the wire plugs into.
