In my syncro non locker, the wiring was there.
I found the locker end in the engine compartment.
The other end was behind the fuse box.   There is
still a small wiring harness needed that was not in
mine that plugs into the fuse box end and goes
to the lock switch panel, and up the the dash
for lighting  power.   One final note the pins
in the connector behind the fuse box, had been
installed incorrectly.
