through 50A fusible link (letter F, located in the fuse and fusible link box)
to BCM terminal 55,
through 10A fuse [No.21, located in the fuse block (J/B)]
to BCM terminal 42.
Ground is supplied
to BCM terminal 52
through body grounds M16 and M70.
When trunk lid opener cancel switch is ON and trunk lid opener switch is ON (pushed)
Ground is supplied
to BCM terminal 30
through trunk lid opener switch terminals 1and 2
through trunk lid opener cancel switch terminals 1and 3 and
through body grounds M16 and M70.
And power is supplied
through BCM terminal 68
to trunk lid opener actuator terminal 3.
Ground is supplied
