Here's why:
* Different Engine Options: 1989 Toyota Pickups came with several engine options (22R, 22RE, 3.0L V6, etc.), and the relay location may vary slightly depending on the engine.
* Location Changes: Toyota might have made small changes to the placement of relays across production years, making a universal answer impossible.
To locate the fuel injector relay, I recommend the following:
1. Consult your owner's manual: The manual should have a diagram showing the location of all relays.
2. Check the fuse box: Most fuel injector relays are located within the main fuse box.
3. Look for a diagram on the fuse box cover: Some fuse boxes have diagrams showing the location of relays.
4. Use a wiring diagram: You can find wiring diagrams online or in repair manuals specific to your 89 Toyota Pickup model and engine size.
Remember: When working on electrical components, always disconnect the battery to avoid potential electrical shocks.
