Are you tired of trying to figure out the wiring on your 55 Chevy headlight switch? Look no further! In this article, we will provide you with a detailed wiring diagram, as well as frequently asked questions to help you get your headlights working like new.
Wiring Diagram
Before we get into the wiring diagram, it’s important to note that the 55 Chevy headlight switch is a 3-position switch, with the following functions:
- Off
- Parking lights
- Headlights
Now, let’s take a look at the wiring diagram:
| Wire Color | Function | Location |
|---|---|---|
| Yellow | Headlight power | Power source |
| White | High beam power | Headlight switch |
| Green | Low beam power | Headlight switch |
| Brown | Tail light power | Headlight switch |
| Black | Ground | Chassis ground |
Now that you have the wiring diagram, let’s take a closer look at each wire and its function.
Yellow Wire
The yellow wire is the power source for the headlights. It should be connected to a constant 12-volt power source, such as the battery or a fuse box. This wire should be connected directly to the headlight switch.
White Wire
The white wire is the high beam power wire. It receives power from the headlight switch when the switch is in the “high beam” position. This wire should be connected to the high beam headlights.
Green Wire
The green wire is the low beam power wire. It receives power from the headlight switch when the switch is in the “low beam” position. This wire should be connected to the low beam headlights.
Brown Wire
The brown wire is the tail light power wire. It receives power from the headlight switch when the switch is in the “parking light” position. This wire should be connected to the tail lights.
Black Wire
The black wire is the ground wire. It should be connected directly to the chassis ground.
