I need a wiring diagram for a 1976 TR7 4 cyl car

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.

It would be easier to pop your head under there and pull out the bulb and see what color the wire is that leads to the bulb.

Use a test lite on negative side of coil, engine cranking, the lite should pulse?
It appears the vehicle has electronic ignition, There is a separate ignition module. In the wiring diagram, I can't guarantee the wire colors. The older my wirings diagrams are, it seems, the less accurate they are. I hope it is readable, If no spark, I'd check the ignition system, Check fuses--fusible links--battery connections.

We have no factory manuls avail to us here at fixya.

Whenever working on a strange vehicle, I visit my local library's reference section. There I can find all types of manuals for different vehicles. I was able to find and photocopy a wiring diagram for a 1976 Cadillac Seville.

Go to faxonautoliterature. They list a wiring diagram manual for your car for $8. They also carry original dealer service manuals at a reasonable price. They have excellent service. Hope this helps.

Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.
