2004 heritage f150 scab v6
today removed a pioneer DVD system & there remains a pink wire i cant identify where it should terminate. here is the connector under the hood near the battery where it originates, runs across the top of the firewall within corrugated tubing & enters the cab in the 3rd photo. can anyone identify what its for & where it should go?






thanks

 

where does it go from the firewall inside the cab?

 

it went to one of the pioneer boxes speed sensor input.
i want to install a stock stereo now, also need a factory connector pigtail.
they hacked off the factory conn

 

that whole congregated tubing is aftermarket

 

thanks.

 

Stock stereo wiring color codes:

Radio 12v light green/purple + radio harness
Radio Ground black/light green - radio harness

thanks for the info.
got it pretty easy & the pink wire was a tap. pulled it out & all is well.
