ok i have an after market head unit but i dont know where to get a harness thing for it so that it fits nicely where my old mach 460 head unit went anyone know where i can get one?

 

oh and i drive a 1997 cobra if it matters

 

well, im not sure with your car but the basic things most cars need are, a wiring harness. it wires to the wires that plug into your aftermarket deck, and then it will plug into your factor plugs to make the deck work. next is an antenna adapter, they sometimes have different sized antenna plug ins so you may need one. last is what i think you mean, sometihng that holds your stereo in place, and fills up the extra space in your dash. these are usually available at local parts store for about 15$ very simple to install, although my mustang (1990) did not need one, it fit in place fine of the factory one. hope this helps..
