I dare you to use the '89 wiring diagram on a '91 with airbags.

I'd be ditching the tire if a sub goes there, I'd never put one under the tire.

I wired the output from the cd to the jack and then from the jack i went to the cd input on the radio. When no cable is plugged in, the cd player works normally. when a cable is inserted, the audio from my phone plays. You have to leave a cd in the player, so the radio will accept input on the audio channel. It works fine on the bench, I have not gotten around to putting it back in the car. I have a spare stock radio in there at the moment.

I would love to put an auxiliary input jack in the system so I could plug in my phone/iPod. I've had the faceplate and top panel off to poke around, but it appears the correct wires are deeper in the stereo's innards.
