Very nice description and pictures. the alarm was giving me a problem on my 400e, so I disconencted it and the car wouldn't start. I tapped the alarm module (you know like you used to tap the tv when the picture shrank, or got squiggly) and it's worked fine since then. (Probably just reseating the connector took care of the problem.)
I would imagine that jumpering the purple wire to the purble/green wire would accomplish the same thing. Now you can remove the relay and little the car up a little.
Or put a kill switch in by cutting the red wire and wiring to +12 via a toggle switch, or secondary key.
Which got me to thinking, why not find the wire coming out of the alarm that triggers the K38 relay? Tie it to ACC and be done. No need for cluster removal.
