As I the continue restoration on my 1972 GS Stage 1 car, I have run across three wires that I need help identifying. All three are within the factory harness that runs from the fuse block to the trunk area and don't appear to be "added" by a previous owner. They do not appear on the wiring diagram. All other connections within this same harness are accounted for (2 side marker lights, gas tank/gauge lead, ground wire to trunk latch brace, plug connector for tail light harness, orange lead for optional trunk light). Other than the trunk light, I can't find any other "trunk based" options that these wires may be used for? These three mystery wires are: two red and one black and have a small pin plug on their ends. Anybody know what these are for?
Adam, That is a solid conclusion. If that was the case, I wonder though, why they wouldn't have run trailer lights off the taillight harness, keeping the connections outside of the trunk.
