Thanks Bob. That=E2=80=99s one of the wiring diagrams I have checked. After s=
ome more investigation, I believe that the pin (which I have determined is b=
lack with a blue tracer) is the horn ground. I assumed that the horns would g=
round to a tab on the chassis but they seem to ground to the horn relay thro=
ugh the wiring harness. Not what the books or wiring diagrams say, but that=
=E2=80=99s the case with my TR6 and I believe it is original. If I go to a 4=
pin relay, I=E2=80=99ll have to ground the horns separately it seems. Thank=
s again for the response.=20
