Some other thoughts:-
Early 5901s listed the lock outputs as + & -.
If yours is one of those, then yes, use diodes, 1N4004, bands towards the 5901.
Here's a little trick that worked on the UK right hand drive versions.
You will need 4 more of those diodes or 6 if 4 door.
With the ignition on OR the driver's door open, test for which wire is the "up" at each switch.
If it goes to NEG rather than positive, or by grounding it with the ignition on you raise that window then this will work:-
Select an aux output, set it up as timed (10 secs. default) and if you want to close the windows automatically on arming, then to enable on arming.
Then feed to a relay, terminal 85 with a diode in line, band towards the alarm.
Constant 12v+ to 86
A good ground to 87
Output from 30, then dioded to each window switch "up" wire as previously tested AND the driver's door trigger which I remember (test) as a BROWN / red.
Program OFF the door open warning chirp on arming.
This will probably give you window close either on arming or enabling that aux separately. Worth a try, window closing for about $7!
In fact you may not even need the relay, depends on the current draw.
Sometimes don't need it on a coupé.
This is assuming the window switches are wired as the coupé, i.e. they trigger a remote relay/processor rather than send 12 volts directly to the windows.
Incidentally the remote start is the EASY part here
-------------
Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.
