What is this cable for?
 

So, I'm getting ready to troubleshoot my intermittent blower motor and I see this strange cable. I'm not sure to were it leads. Looks like some kind of sterio or AV cable. Thoughts?

That is for the factory cell phone option. Most 80s models got them. It runs to the trunk.

It's a PL-259 connector which was used in the U.S. for CBs. Most American cell phones (Motorola had the biggest market share) of that era used the TNC connector.

I just picked up an 81 SD and saw that too while I was cleaning up the trunk and was going to post the same question and same pic. :eek:

Thanks!!!
