Trunk Light

[Cam shaft]

Would the trunk light harness,  C9ZB-13550-A (1970 gt500,), require an additional ground wire for a correct installation ?

Thank you

only on fastback all fiberglass hood since the verts had metal bottom side to ground.

thank you Ed.

We are going to use a 14 gauge black wire following the same route as lite socket wire, connected to socket  with screw and washer. The question remains,  where and how is it  connected to the body to complete the circuit?

thank you again
