What components are shown in this two-speed fan wiring diagram?

The diagram shows a Fan, a Thermo Switch, a Relay, two 2-Pin Connectors, and a 1-Pin Connector, all interconnected by color-coded wires.

What wire colors are used in this fan wiring diagram?

The diagram uses brown, red, red with a white stripe, red/black, green, and blue wires to show the circuit connections.

How is the thermo switch wired in this diagram?

The thermo switch has three wires: a red wire, a green wire that runs to a 2-pin connector, and a blue wire that ties into the relay and a 2-pin connector.

What connects the fan to the relay?

A red wire with a white stripe runs from the fan to the relay, and both share the brown wire run along the bottom of the diagram as well as red power wiring.

Does the diagram show fuse ratings or terminal numbers?

No. The diagram contains only component labels and color-coded wires; no fuse ratings, terminal numbers, or part numbers are shown.

This document is a hand-drawn style, color-coded wiring diagram showing how to wire a two-speed radiator cooling fan circuit, uploaded to a 1983 Volkswagen Rabbit gallery under the filename "2SpeedFan.jpg". The diagram contains six labeled components: a Fan, a Thermo Switch, a Relay (drawn with internal switch and coil symbols), two 2-Pin Connectors, and a 1-Pin Connector. Rather than text callouts, wiring is conveyed entirely by wire color: brown wires form a common run along the bottom linking the fan, relay, and one 2-pin connector; blue wires link the thermo switch, relay, and a 2-pin connector; a green wire runs from the thermo switch to a 2-pin connector; a red-with-white-stripe wire connects the fan to the relay; and several solid red and red/black wires distribute power among all components, including the 1-pin connector. Semicircular jumps in the drawing indicate wires that cross without connecting. The diagram contains no part numbers, fuse ratings, terminal numbers, or year/model identification. A reader can learn the overall wiring topology and wire colors needed to install or troubleshoot a relay-controlled two-speed electric fan with a thermo switch.
