What wire color feeds the Samurai rear tail lights and side marker lights?

A red/yellow (R/Y) wire supplies power to the rear combination tail lights, rear side marker lights, license plate lights, and the trailer connector; all lamps ground through black (B) wires.

Which connectors are used for the rear combination (tail) lights?

The LH rear combination light uses connector L18 (power in at pin 1, ground out at pin 5), and the RH rear combination light uses connector M01 (pin 1 in, pin 5 out).

Where do the license plate lights get power and ground?

The LH license plate light is connector O09 and the RH is O07; each receives R/Y power at pin 2 and grounds through pin 1 on a black wire to chassis ground point 12.

How do the tail and side marker lights ground?

Their black ground wires join and pass through connector M07/L16 at pin 7, then run to chassis ground point 11.

Is there a trailer wiring connection shown?

Yes — the R/Y tail lamp feed branches to connector L20 pin 5, labeled TRAILER.

This document is one page of a factory-style wiring diagram (uploaded as "Clearance Lamp2.gif") showing the rear clearance/tail lamp circuit for a Suzuki Samurai. Power arrives on a red/yellow (R/Y) wire from an off-page connector (symbol 7) and branches to a trailer connector (L20, pin 5), then passes through connector L16/M07 (pin 4) before splitting to feed the rear lighting: the LH rear combination tail light (connector L18, pins 1 and 5), LH and RH rear side marker lights (connectors M06 and M02, pin 2 in, pin 1 out), the RH rear combination tail light (connector M01, pins 1 and 5), and the LH and RH license plate lights (connectors O09 and O07, pin 2 in, pin 1 out). All lamp grounds return on black (B) wires: the tail and side marker lamps ground through connector M07/L16 (pin 7) to chassis ground point 11, while the license plate lights ground at chassis ground point 12. A small legend block lists connectors M03/O01 and M11/O12 with pin numbers. Useful for tracing tail light, side marker, and license plate light wiring, connector IDs, and ground locations.
