'94 UrS4/UrS6 ABS Switch Mod

    I've just completed a mod to add an ABS switch to my '94 UrS4. This mod
will work with the '94 UrS4 cars which have the later EDL type ABS
controller and the UrS6 cars . The '93 UrS4 requires a different approach
that I'll let someone else pioneer :o)
    The mod on the '94 looks OEM since it uses the OEM ABS switch faceplate
from the 200 series Type 44. The faceplate is not an exact match for the new
style faceplates in the UrS6.
    The mod uses a NC relay to interrupt the ABS controller power feed from
the fuse panel. It works like a charm.
    I'll post a "how-to", probably after the holidays.

    I also installed the programmable intermittent wiper relay  ( P/N 3B0
955 531  CDN$55 from my dealer) while I was in there. Slick!

    Merry Christmas to all! Motor safely this holiday season!
