Yea, doing it myself had definitely crossed my mind, especially since there's already a kenwood aftermarket in there, so I figure whatever harness I would need to fit it to a stock stereo will already be there.
As for you guys helping me, even tho I'd love that itz not for a f-body, itz for a mustang

Itz a long story but main point is I don't have enough money for an LT1 yet and my brother in law finally got 'round to makin this stang driveable (he took it off the street for a year or so) so I more or less got it for free. Now itz a matter of deciding whether to get an LT1 this summer, I'll get enough cash working by then, or put some money into this stang and just save up to get a 5th gen in 3 years or so
