Headlight wiring

This should have been easy to figure out. Just look at the wiring diagram. You can download manuals here:

First, look in the instrument panel wiring and discover which dimmer switch wire branches off to feed up to the HIGH BEAM INDICATOR on the dash

This gives you the wire no and wire color, and so the matching one out at the headlight plug is your high beam

The ground is marked

And that, my friend, is exactly what these manuals are for

In the 71 manual for download, this manual is one where the pages are consecutive, so you must play with page numbers. The electrical index is page 368

They show page 160-161 is for the Valiant, but this is EIGHT dash 160, (8-160) on the paper, but in your viewer this will be page 381

Find the dimmer, "look it's marked!!" L3-18R is the high beam, L4-18V is the low beam

Now all we need is the front end lighting diagram, and whoops!!! it's not IN the 71 Chassis manual, so let's go have a look at the 71 BODY manual

This time it's chapter 5, body electrical, but we must once again play with page numbers. This time we go to page 135, which is the index. We see front end lighting for the Dart is page 5-46, and that ends up being page no 138, and there you are.........The red L3 wire, and they show you the black ground wire
