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.

I had the cluster out since my odometer was not working, fixed both at the same time...

I liked to do it this way in case the next owner decides to fix the alarm correctly...if i it gives me trouble, i will make it more permanent...The reason for this write-up is to document in pictures the wonderful advice given to me here, and to help some other people also who might be unsure about how to do this

This thread is where i got the info from, this is such a great forum..

A 1992 and earlier does not have the K38 starter lockout relay (the one behind the instrument cluster). To disable the alarm just unplug in under the passenger footwell and operate the vehicle as usual.
