This is page SD110-2, 'Power Distribution (2)', of a wiring diagram showing battery power distribution through the engine room (E/R) junction boxes RH and LH. The RH junction box receives battery power through connector E and a B+ 50A fuse, feeding the F/PUMP 20A fuse (through the F/PUMP RELAY via connectors CHG97 for G4KF engine or CLG97 for G6DA engine) and the ECU-1 10A fuse, with outputs routed to the TCM and ECM via connectors EC21, CLG-ZF, ELG-A, CHG-T, and CHG-K. The LH junction box receives battery power at connector A and feeds the H/LP (HI) 20A, B/UP LP 10A, H/LP (LO) 20A, and HORN 15A fuses, each controlling their respective relays (E58, E57, E59, E60). Downstream of the H/LP (LO) relay are the H/LP LO LH 15A and H/LP LO RH 15A fuses. Outputs run through joint connector JE70 to the instrument cluster (M11-A), DRL resistor (E09), headlamps LH (E95) and RH (E96), and headlamp leveling devices (E92, E99). Wire colors (R, P, W, P/B, Gr, Br, L/B, R/B, Y/O) and HID vs. non-HID wiring variations are noted. References to related pages SD110-1, SD110-3, SD110-5, SD110-8, and SD110-9 are included.

Frequently asked questions

What amperage is the headlamp low beam fuse on diagram SD110-2?
The H/LP (LO) fuse is 20A in the E/R Junction Box LH, and downstream of the H/LP (LO) relay there are separate H/LP LO LH 15A and H/LP LO RH 15A fuses.
What fuse feeds the fuel pump relay?
The F/PUMP 20A fuse in the E/R Junction Box RH feeds the F/PUMP RELAY, via connector CHG97 (G4KF engine) or CLG97 (G6DA engine).
What size is the horn fuse and which relay does it use?
The HORN fuse is 15A, feeding the HORN RELAY at connector E60.
How does the headlamp wiring differ between HID and non-HID?
The wires to the headlamps differ by color: one circuit is P (With HID) or R (W/O HID), and another is Y/O (With HID) or P (W/O HID), running to headlamp connectors E95 (LH) and E96 (RH).
What is the main battery feed fuse in the E/R Junction Box RH?
A B+ 50A fuse receives battery power (from SD110-1) via connector E, feeding the F/PUMP 20A and ECU-1 10A fuses and an output to ECU 30A (SD110-3, SD110-5).
