Your best bet is to:
1. Consult your owner's manual: It might have a diagram of the fuse and relay box locations.
2. Check the underhood fuse box: This is the most common location for relays. The box is usually near the battery. Look for a diagram on the inside of the fuse box lid – it should identify the relays.
3. Check the passenger compartment fuse box: Some vehicles have additional relay boxes inside the cabin. Again, check for a diagram on the inside of the box lid.
4. Use a wiring diagram: A wiring diagram specifically for a 2000 Acura RL 3.5 will show the relay's location. You can find these online (sometimes for a fee) or at auto parts stores. Search for "2000 Acura RL 3.5 wiring diagram".
5. Search online forums: Acura enthusiast forums might have threads discussing fuel pump relay location for this specific model year.
Important Note: Before working on any electrical components, disconnect the negative (-) terminal of the battery to prevent accidental shorts or damage.
