The one on the metal frame under the dash is for the turn signals. I had to troubleshoot it many moons ago. Changed the 4 way relay 3 times until I figured it out! The turn signal flasher was the original from '79, it was light blue plastic and everything. Replaced it with an Basic Wiring Harnesses for 1977-81 Trans Ams It's not unusual to find that the wiring on your project Trans Am has been hacked to pieces or even on fire. The instrument panel (IP) harness is a huge mass of spaghetti growing out of the fuse block the fuse block was totally redesigned, so the 1980-81 harnesses will not mix with the 1970-79.
