There are four main wiring harnesses in a Datsun 1200.
Contents |
Overview
The four main harnesses:
- 24012 Engine Room Harness (includes front light wires)
- 24013 Instrument Harness (dashboard)
- 24014 Body Harness: goes from firewall to rear of car, under floor mat
- 24015 Tail Harness (rear lights)
Generally speaking, the main difference between LHD and RHD harnesses is in the Instrument Harness, with the dash gauges and switches being on opposite sides of the car.
Changes over time include:
* 1972: USA changed to electric choke with relay * 1974: alternator moved to opposite side of engine * 1978: Australia changed some connectors to tab-lock * 1978: Japan changed some connectors to Pin type * 1989: Feedback Carburetor with ECU

Engine Sub-Harness
On newer 1200s, ENGINE ROOM SUB-HARNESS ASSY is the branch that goes down to the transmission. Starting October 1975.
The sub-harness is a small harness that connects to the starter motor, reverse light switch, etc. Connects to Engine Room Harness (engine compartment) via a circular pin connector.

After the April 1971 rationalization, only four harnesses were used:
* STD/DX [rectangle gauge] * GL/GX [round gauge] * Automatic [round gauge, with kickdown switch plug]

Before April 1971 many harnesses were used: (3,4 or Auto) and (DX/STD vs GL/GX) and "cold option" versions of every one of those.
- Cold Region (寒冷地向) may have wiring for heater?
- STD is square gauge, GL/GX is round gauge, DX-Sedan/DX-Van is rectangle, DX-Coupe is round
