Electrical: oem connector behind radio

Hello, quick question. Behind and a little below the radio there is a blue connector (has that thin foam wrap on it) with a single connector coming out of it. Pretty sure it connected to the rear speaker harness but its on a seperate line, you can almost always see what im talking about when people remove the bottom console cover (dangles right above a control module) What does this control?

 

Got a pic? Did you try unplugging it to see what stops working?

 

yeah in the stickies, the diy mods on page 7 post #122 a guy added a usb port. you can see the connector in some of those pictures. I cant test it myself yet as im currently removing a bunch of electrical / excess junk. ill take my own pictures when the sun comes up.

 

Took a look at the picture and couldn't see what you were talking about. Will be waiting for your picture

 

Power antenna would be my guess.

 

I was thinking if hes manual maybe the auto shifter light connector?

 

The blue connector behind the radio is usually for rear speakers.

 

This wire? I've read it connects to the rheostat and then grounds. Leave alone.

 

yeah that looks like it lemmie run down stairs and get a picture, It goes into the rear speaker harness (i wont be using rear speakers so i left it unplugged)

 

https://postimg.cc/gallery/11451d1qa that rear harness was spliced, he had some black box on it some sort of converter . hope the link works

 

Should be ok to leave alone. Probably just dimmed the factory head unit.

 

sweet thanks my dude. now off to ask more wiring questions heh.

 

A service manual wiring diagram is the best resource. Be sure to get one specific to your year.
