You may have the wrong headlamp buckets. The early TR4 type hasn't been
available for many years, and the later types sold as replacements need a
different type of rim.

On an early TR4 like yours (and mine), that's all there is. The top
section of the column is grounded via the straps across the rubber
U-Joints, and thus to the steering rack, which is solidly mounted to the
chassis.
Troubleshoot by connecting one end of a long piece of wire to the grounded
battery terminal. Have someone hold down the horn button. Starting at the
rack, touch the other end of the wire to each column segment and each
grounding strap until the horn blows. When the horn blows, you'll know
that the broken ground is right below that point. If you get to the top
of the column without the horn blowing, then the problem is probably the
switch itself - either the spring-loaded contact brush, or the wiring.
