Ground wire on 72 Rallye Tailights ?

[ACUDANUT]

My rear tail lights are not working right.   Where are the proper grounds for these ?

If your '72 is like my '74, there is a ground lug in the harness just after the harness enters the trunk cavity (maybe six inches in).  It gets attached to an angular shaped bracket that goes from the rear to the trunk floor.  When I was rebuilding the tail light assemblies I tested them using this ground lug and all worked perfectly.

Good Luck with your search..

Depends on which taillights you have. The Rallye taillight housings are metal and the sockets ground themselves. The other housings (at least in '71) are plastic and require extra ground wires, one which, in a '71, attaches to the rear of the driver side of the trunk.

There is, but that fat chick you always post up sat on it and its disappeared.

Mine are Rallye Tailights. I wonder what is keeping them from getting a good ground.  
What happened to black wires on cars always being Negative/ground wires.

Well, I have brighter taillights, but I tapped into the running lights (by mistake)  Now I do not have running lights and side markers lights.  Errrrr

My 72 rt tailights had a ground wire on the passenger rear assembly to to the mounting stud of the side rear marker.

Rallye, R/T lights all have a ground wire on the drivers side trunk area. So I am still wondering what is going on.
