Hey man there are two easy ways to mount it. I mounted mine in the righjt drivers side quarter trim. You can also buy a mounting bracket from UPR here is click on my car homepage below and look at the pic link.
No it was fairly easy I did however have to go to ford to get the wiring schematics. The aftermarket ignition is pointless the damn thing doesn't ever work. I have mailed it back to them 4 times now. I bought a new interior molding piece before I mounted that tack also
