I pulled the stock stereo out tonight to see what harness I need. I was looking at 2003 f150 stereo harnesses. It looks like the they only have 1 square connector, my stereo has 2 square connectors on the back. Does anyone have the correct part numbers that I would need? I'm trying to find a metra or scosche kit but have had no luck.

metra harness 70-1771, the extra plug is your changer most likely... do you have a factory sub?

 

I have no clue. I haven't found a changer. I would assume it's behind the driver's side rear seat. Nothing there but an empty compartment. Only have the truck a few weeks, haven't torn anything apart yet.. I got a basic build sheet from Ford, all it says is cd, cassette stereo.

 

yea they have changers, but never had factory subs

 

Where do they usually hide the changers?

When I hit the cd button twice, I get a NO CDDJ. So I assume no changer. Maybe it's an amp. I'll have to look tonight.

probably pre-wired for a changer

 

Ok, thanks. Called around for an adapter. None to be found. Looks like I'll have to order one online. Thanks for all the help.

yea its pre wired, you dont have a changer, and i believe it is in the back wall behind the drivers seat.
