Which wire is the reverse light on the Cavalier?
2 Answers
The wire used for the reverse light on the Cavalier can be tested with a multimeter. First, locate the ground wire, then turn on the reverse light, and use the multimeter set to the 20V voltage range to measure each wire. The one with power is the corresponding light that is turned on. The Cavalier is a compact sedan under SAIC-GM Chevrolet, with body dimensions of 4474mm in length, 1730mm in width, and 1471mm in height, and a wheelbase of 2600mm. The Chevrolet Cavalier comes in five colors: Pearl White, Peacock Blue, Agate Red, Amber Brown, and Crystal Black. In terms of appearance, the Cavalier adopts Chevrolet's family design language, featuring a sleek body proportion and a family-style front face with a dual black grille. On the side of the body, the Cavalier Redline series uses black window trim, paired with exclusive smoked outer rearview mirrors, red decorative strips, and 16-inch black alloy sport wheels with red logos.
I previously owned a Cavalier and needed to locate the reverse light wire to install a backup camera. Typically, within the rear taillight assembly, the wiring harness has several color codes - the reverse light wire is usually blue or blue with a white stripe, indicating negative control, but this can vary by model year and trim. The most reliable method is to use a test light or multimeter to check for voltage when the transmission is in reverse gear; the wire that lights up is the reverse light wire. Avoid tampering with other wires, as incorrect connections may blow fuses or cause short circuits. I also recommend consulting your owner’s manual, which often includes wiring diagrams, or checking automotive forums for shared experiences from other owners. Before DIY work, ensure you have all necessary tools and prioritize safety.
