Contents of wiring diagrams
On the electrical circuits presented in this manual, the symbols given below are accepted.
Note: the presence of an inscription in the scheme (): HV-Type or []: MR-Type, or {}: Sirius D4 indicates that round, square or curly brackets enclose the pin numbers of the engine control unit connectors of the types indicated in the note. Practically, until now, all Chevrolet cars produced in Ukraine were equipped with HV-240 type blocks.
A: The upper horizontal lines are power supply lines under various conditions:
- Circuit 30 - supplying power directly from the battery, bypassing the ignition switch.
- Circuit 15 - power supply with the ignition and starter on.
- Circuit 15A - power supply with the ignition on and the starter off.
- Circuit 15C - power supply with the ignition on and mode "ACC".
- Circuit 58 - power supply to the lighting circuit at positions 1 and 2 of the light switch.
IN: Ef20 - fuse number 20 in the fuse box located in the engine compartment. F2 - fuse number 2 in the fuse box located in the passenger compartment.
WITH: Connectors (C101 - C902) (see description of connectors).
D: Cable splices (S101 - S303) (see description).
E: Internal Circuits of Circuit Components (relay) indicates the name of the component and the pin number in the connector.
F: Internal Circuits of Circuit Components (switch) the name of the component, the pin number in the connector and the circuit of external connections are indicated.
G: Abbreviations for wire insulation color.
H: Bottom horizontal line: ground line on "mass" (G101 - G401) Designation B means chassis ground (body).
