so the other night i hacked up my 88-89 harness from the fuse box side of the harness, and made it a complete 90-91 harness, that is plug in and play. Everything worked with testing Cluster lights, clock etc... Once i installed the dash, and i notice this last night. I have no cluster lights. Everything else works fine. What fuse is this located on? Also don't the tail lights usually go out when the cluster lights go out? Could this be a bad dimmer switch?
