Start by locating the OEM harness behind the factory head unit–typically a 12-pin rectangular connector with color-coded leads for power, ground, speaker outputs, and data signals. Use a multimeter.

Start by locating the connector harness behind the dashboard–typically a 10-pin plug with color-coded wires. The power feed (red) and ground (black) are critical; verify continuity using a multimeter.

Locate the 16-pin connector behind the factory stereo unit–colors follow a strict code: yellow (constant 12V), red (switched 12V), black (ground), orange (illumination), and blue/white (power antenna/amplifier). Disconnect the.

Replace a faulty bulb socket or upgrade to LED assemblies only after verifying the circuit integrity behind the housing. Start by disconnecting the negative battery terminal–this eliminates risk of.

Begin troubleshooting with the underhood fuse box (IPM) located on the driver’s side near the battery. Pinpoint relay positions–R03 (fuel pump), R05 (A/C clutch), and R09 (horn)–using a multimeter.

Locate the C2 connector behind the dashboard lower trim panel–pinouts follow the purple, pink, dark green, and light blue/red stripe wire sequence. The A11 terminal carries constant 12V supply.

Locate the main power feed at terminal B+ on the rear of the generator–this connects directly to the battery’s positive terminal via a 6-gauge red cable. Trace the white.
