TBH, this kit isn't really intended for cars with an existing system as sophisticated as that fitted to the E30, but it should be possible to configure it to work.
Find the lock request and unlock request wires behind the glovebox area, where they come out from behind the speaker, and strip the insulation off of a half inch section of each, so that you can make a 'tee' connection to each.
Fit a ring terminal to the brown wire of your unit, and connect it, along with the black wire to the earthing stud behind the glovebox.
Connect the red wire to the red/yellow from the accessories socket, then experiment with connecting the yellow, white, pink and blue wires, one at a time to either the lock or unlock request wire, until you find one that works. Do the same with the other request wire, and then cut off the other two wires that are left over.
