Headlight grounds

So the left side travel's over to the right side then up to rad support
That's how I remember it, but its been a while. My headlight harness is modified - did that before digital camaras were cheap.
let me see what the assembly drawings show.
Looks like location of the harness is up across the top (under the lip) and then grounds lead(s) drop down to screw.

For educational purposes, I've marked this up to explain better what I'm looking at. You can buy this book if you want from Faxon.

D in the box labeled Model is for 1968, L is Dart and the O indicate it applies to all versions.
But the Dart's front looks to have the welded cable clips marked 6 (in triangle) slightly different than the Valiant and Barracuda.
View X shows the welded clips across the 'radiator yoke crossmember ( E in square) get bent up to retain the cable.
