Bike: Todd’s CB350.

The new signals have two wires, a ground (black/white) and power (black). This is different than the stock signals which only have a single wire (power) running out of it. This is because the bulb socket is grounded to to the metal signal housing which is grounded into wiring harness through the headlight ear bolts (green wires connected to the bolts inside the headlight ears). These can be removed since the black/white will be used as the ground instead.

The black wires connect into the light blue (right side) and orange (left side). The black/white connects to green.

Installed!

Note: If you have a later model CB, the front signals are also running lights. This means you’ll need signals with 3 wires: gound, power, and flasher. The extra wire will connect into the blue/white or orange/white wire from the harness.
