Turn Signal Relay Circuit Diagram

Variety of universal turn signal wiring diagram.

Turn signal relay circuit diagram.

The turn signal circuit gets power when the ignition key is on. A quick and cheap way that works just as good is a tail light wiring converter for trailers. The power goes through a fuse panel into the thermal flasher. They look like this.

Pulsed to steady output turn signal output to steady output for duration of turn signal relay wiring diagram. This will give you a steady output while the turn signal is on. Externally the only difference is in the connection for the dash indicator. A wiring diagram is a streamlined standard pictorial depiction of an electric circuit.

If you have cornering lights and want them to come on only when your turn signal is on and you do not have a steady output use the following for each side. It shows the parts of the circuit as simplified forms and also the power and also signal links in between the devices. You can get them at places like napa or here. Most common problem sources include bulbs wires connectors fuses flasher units and switches.

From there it goes to the stalk on the steering column. Turn signal problems and diagnosis can get confusing especially when a system shares wires and connections with the parking warning and braking light systems. Later the 4 terminal flasher relay was replaced with a somewhat simpler 3 terminal design. This diagram shows the turn signal flasher circuit in its simplest form.
