Reconnect the wire and look for another wire.
Many domestically-made GM vehicles use Type A locks. However, many more GM vehicles are Type C than in pre-
vious years. The full-size pickups (1989-later), many of the S10 Blazers, the Corvette, '95 Cavalier/Sunfire 1993
and newer, Camaro/Firebird all use Type C door locks, and cannot be controlled without a 451M! Almost all domes-
tically-built Fords are Type C. Ford builds almost no Type A systems. Chrysler builds both Type A and Type C, so
test carefully.
IIMMPPOORRTTAANNTT!!
Remember that the functions of these wires reverse between Type A and Type B!
