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
