The Standard Color Legend:

• B = Black (Earth/Ground - always check for resistance to chassis)
• R = Red (Constant battery positive / Alternator output)
• W = White (Alternator sense / Heavy current)
• G = Green (Switched ignition signals / sensor signals)
• Y = Yellow (Airbag system / Illumination)
• L = Blue (Various control circuits)
• Br = Brown (Tail lamps / Parking lights)

Critical Wire Color Codes for Proton Wira

Before diving into a specific diagram, memorize these standard colors. These are consistent across nearly all Wira models (1993–2009):

| Color Code | Meaning | Typical Circuit | | :--- | :--- | :--- | | B | Black | Permanent Ground (Chassis) | | R | Red | Permanent Battery +12V (Unfused or Main Fuse) | | B/Y | Black with Yellow stripe | Ignition-switched +12V (Run & Start) | | B/W | Black with White stripe | Ignition-switched +12V (Accessory & Run) | | W | White | Alternator output / Charging circuit | | G | Green | Tail lights, License plate lights | | G/W | Green with White stripe | Right turn signal / Brake switch output | | L/R | Blue with Red stripe | Headlight (Low beam) | | L/W | Blue with White stripe | Headlight (High beam) |

Pro Tip: If a diagram shows "B/Y" at pin 3 of the ignition switch, you know it should have 12V when the key is turned to "ON."
