Where can I find a circuit diagram for M&S model MC350 system?

I'm sorry, but as a text-based AI model, I'm unable to provide visual images or diagrams. However, I can try to explain the general wiring setup for a 1976 GMC Jimmy.

The wiring diagram for a specific vehicle can vary based on the model, trim level, and optional equipment. It's recommended to consult a service manual or reach out to a qualified automotive electrician for accurate and detailed wiring diagrams specific to your vehicle.

In general, the wiring in a 1976 GMC Jimmy would consist of various circuits for different systems such as the ignition system, lighting system, charging system, and more. Here are some common components and circuits you might find:

1. Ignition System: This circuit includes components like the ignition switch, ignition coil, distributor, spark plugs, and related wiring. It controls the ignition timing and provides sparks to ignite the fuel-air mixture in the engine.
2. Lighting System: This circuit handles the headlights, taillights, brake lights, turn signals, and other exterior and interior lights. It usually consists of a combination of fuses, relays, switches, and wiring harnesses.
3. Charging System: The charging system includes the alternator, voltage regulator, battery, and associated wiring. It generates electrical power to charge the battery and provide electricity to the vehicle's electrical components.
