First, let me say this is NOT applicable to all E30s. Generally, Late Model (88+) will have this wiring on premium sound cars. IF you have a fader in the dash, this MAY work: you need to unwrap about 8" of fader harness to see if you have 4 pairs of speaker wires, as some cars have only 6 wires, not 4 pairs (8 total) so if this chart does not apply PERFECTLY to your car, don't use it.
Quick disclaimer: this is not idiot proof. You mess it up, don't whine at me, I do not care.
If this saves you countless hours of hassle or you are just feeling generous, feel free to paypal me a tip. Add "@gmail.com" to Stereoinstaller1 and I promise to only use the money for projects on my car.
OK, here is the info.
Obviously, what you do here is simple: connect the "deck" wire to the "dash" wire, then back at the trunk, connect that "dash" wire to the "speaker" wire.
This is not rocket surgery, boys. Get it done.
