Esc module location 94 Chevrolet 1500 and wire color for knock sensor?

There isn't a single, universally located "ESC module" in a 1994 Chevrolet 1500. The Electronic Stability Control (ESC) system as we know it today didn't become standard until much later. A 1994 model likely wouldn't have a dedicated ESC module. It might have components that contribute to stability control, but they'd be integrated into other modules like the ABS module (Anti-lock Braking System).

Regarding the knock sensor:

The knock sensor's location and wire color vary slightly depending on the engine in your 1994 Chevy 1500 (e.g., 4.3L V6, 5.0L V8, 5.7L V8, etc.). You'll need to consult a wiring diagram specific to your truck's engine.

To find this information:

1. Identify your engine: Check the engine bay for an identification plate. This will tell you the exact engine size and type.

2. Obtain a wiring diagram: You can find wiring diagrams at these sources:

* Online repair manuals: Sites like Chilton, Haynes, and others offer repair manuals (often requiring a purchase) with detailed wiring diagrams. These are your best bet for accuracy.

* Auto parts store: Many auto parts stores can provide wiring diagrams (sometimes for free, sometimes for a small fee) if you provide your vehicle's information.

* Online forums: Chevy truck forums (e.g., on sites like ChevyTalk) may have members who can help if you provide your engine details.

Once you have the diagram:

The diagram will show the knock sensor's location on the engine block and the wire colors connected to it. The sensor itself is usually a small, threaded device mounted near the engine block.

Caution: Working with automotive electrical systems can be dangerous. If you are not comfortable working on your vehicle's electrical system, it's best to take it to a qualified mechanic.
