if u want to do it truely right go to a stereo shop they usually sell the plug for radios, u can get the factory one and the one to plug into the factory one to wire to the radio, thats what i would do...all in all u might spend 40 bucks...that would put it bad to the way it origionally was the metra plug numbers are 70-7712 and 71-7712 any shop should have them in stock and if they dont carry metra they should be able to crossreferance to whoevers brand they carry
