installing after market stereo into bose equipped caddy

[grayciey]

I bought a 1990 cadillac eldorado. I love it, only 70,000 miles, canary yellow color, canary yellow leather interior runs like a top and I got it at a steal of a price. Only thing, It has the original stock stereo and the tape deck is broken, all I can listen to is a few crappy radio stations with poor reception. so I want to put my panasonic deh 1500 cd player I bought a few years ago in. I bought the scosche gmda wiring connector. (Even though the package calls for a different connector for my year car, when I tore the dash apart the first time i realized that the gmda connector had the correct plugs for the factory wiring.) Now the back of the connector scoshe package says for bose equipped vehicles I have to purchase the scosche fai-3a bose interface. My question is Do I HAVE to. I called an audio place and they said they are a special order item and alot of times they work without them. So I am wondering if anyone knows if I can just plug in the gmda harness and skip the interface all together. before I rip my dash apart again on just the chance it will work without it. thanks in advance

try it and find out. but you could replace all the speakers and just run new speaker wire and only have to tap into power,ground,antenna, switched and you would be good.

Match your harness up to the stock plug and look at all the speaker wires. If each speaker wire in your harness lines up with a wire in the stock plug, then you can try just hooking up the head unit like normal (making sure the "power antenna" wire in the harness is connected to your head unit's remote output). It might work, it might not.

If there are speaker wires in the adapting harness that line up with empty pins in the factory plug, or if any speaker wires line up with a "drain" wire (silver-colored wire in a transparent jacket) then you'll need the premium sound adapter piece, or you'll need to replace the speakers and do some rewiring.
