I installed a manual Gen2 steering wheel in my Gen1 997 Turbo.
Managed to get the horn working with the following.
From the rear of the connector, pop off the yellow cover.
Cut top row black wires as shown below.
Join wire 1 with a crimp connector and self tap screw into the steering wheel.
Wire 2 extended connected onto the rear of the air bag with a spade connector.
Wire 1 horn works with ignition / engine running.
Wire 2 horn works with ingnition off, key removed.
