The twin horns on a TR3 have two electrical connections each. The wiring =
diagram shows these as Brown with Green tracer and Brown with Black =
tracer. Is there an orientation to which wire attaches to which =
connector on the horn? If so, what is the impact of attaching them the =
wrong way? As always, thanks for your input and feedback.

Yes, it does.  The horns ground through the horn button and when the contac=
ts get old they don't carry enough current to work the horns.  A quick fix =
is to wire up a relay.

Get a generic cube relay a your FLAPS.  To wire up the relay connect one co=
il wire to the N/G wire and the other to the N/B wire from the steering col=
umn.  Connect the N/B wire from the horns to the NO contact on the relay.  =
Connect the COM contact on the relay to a good ground.  It's a walk in the =
park.

I have power at the N/G bullets and connectors. When the N/G wires are atta=
