Introduction
Yesterday, I followed some tips found elsewhere on the internet to disable the security alarm on my 1985 300sd MB. After driving over 30 miles in suburban traffic with the intermittent sounding of the annoying horn and light show the whole way it was time for this "system" to go. This is for a US market 300sd others may vary.
