it may have had its time.  There are a couple of options you can try before writing it off though.  Third generation and earlier cliffords were very succeptible to voltage variations and spikes and would lock up.  A simple "computer style" reset often solves the problem  Those are the two fuses you need. They connect to  red and RED / white wires.  First off check the ground for the system(black 18 gauge wire).  It should be at or near the battery too if it was done correctly.  Make sure you did not accidently not reconnect it if you disconnected the negative battery terminal   After verifying that pull the 5 amp fuse at the battery and let it sit out for a minute, then reinstall.  See if you can get into valet after that.  Even if it goes into valet, there is a good chance the remotes need to be reprogrammed.  Older cliffords were notorious for dropping remotes after removing power.
