**help needed as asap as possible**

[MachToLoud1]

So I'm getting ready to install my after market radio on my 03 cobra that I previously had on my 04 Mach. I've been reading on different sites that I need the METRA 70-5701 and the 70-5700, my question is which one did you use??

The stereo I will be installing is a Pioneer DEHX6600BT

thanks in advanced.

Both are wrong I used the one from crutchfield 70-5521
