I used the wiring harness adaptor to install mine so I didn't have to deal with different wires out side of hokking up the adapotr then plug and play. Does your new radio have a power antenna option? If not you will have to wire the it to a keyed power source if it does then you can isolate the power source and it should work when you turn the radio on but not when you have the cd palyer going. (at least that is how mine is set up) Finding the wire for the power antenna shouldn't be too hard. Good luck.
You have to get an antenna adapter. GM uses a small antenna end. Aftermarket stereos use the large ends. It is usually 12" long with the GM female on one end and the large male end at the other end. Circuit City's to Walmarts carry them.
actually thats the problem there is no attena plug it the corvettes only from 92 - 96 i know it sounfds weird but ifd you own a 92 - 96 corvette anfd you pull out your radio you will notice that there is no attena but there are two wire harneses i had a 87 vette and had no problem just seeing if any one installefd a after market radio into a 92 - 96 vette thanks for the input though
ok its done heres the scoop if your going to install an after market radio in a 93 - 96 corvette , there is a main amp mounted under the passenger side storage bin that is also were you will have to run your wire loom from but thats were the attena plugs in also so i just got a attena extension and its done i put the pioneer indash tv / radio with 4 12inch alpine type r subs with the R/F punch 1000 amp i'll post some pics tomarrow it looks sweet
