I bought a factory ford sub and amp combo,but my truck didn't come with the factory plug that plugs into the sub amp combo........Can somenone tell me where i can find the plug that plugs into the sub unit. I don't want to do aftermarket

 

I have remove all the carpet to see if it was there and i knows its not......so thats why i just want to find out where to get one and whats the part number.
