2007 Acura RL Electrical Schematic – Factory Manual

If you’ve ever chased an electrical gremlin on an Acura RL 2007 Electrical Schematic job, you know the drill—spend an hour digging through aftermarket wiring books that skip half the relay locations, then find out the one you need isn’t even listed. I’ve been there. That’s why this OEM factory manual exists. It’s the same binder the dealer techs used, and it doesn’t leave you guessing which fuse box holds the SH-AWD relay or where that turn signal sounder hides behind the dash. 215 pages, factory printed, and built for real bench work.

Buzzers, Relays & Timers Location – Page 1 Breakdown

Right on page 1, the manual drops the full location table for every relay and buzzer in the RL. Need the Fuel Fill Door Opener Relay? It’s in the passenger’s under-dash fuse/relay box, component (5). Adaptive Cruise Control Relay? Auxiliary under-hood relay box, see Fig. 187. The Keyless Answer Back Buzzer lives behind the middle of the rear bumper. No aftermarket PDF gives you that kind of pinpoint accuracy. You get the exact component number, fuse/relay box name, and a figure reference so you can put your eyes on it without flipping through thirty pages of generic diagrams.

Circuit Protection Devices – Where Fuses Hide

Section two maps circuit protection devices: the Battery Terminal Fuse Box (+), Auxiliary Under-Dash Fuse Holder, Under-Hood Fuse/Relay Box, and more. Each location is tied to a figure in the manual, so you’re not prying open the wrong panel. This section alone saves you the time most DIYers waste pulling the driver’s kick panel when the real problem is in the passenger’s under-dash relay box.

Control Units Location – Don’t Pull the Wrong Module

Control units are scattered across the RL—behind the left kick panel, under the dash, in the engine compartment. The manual lists every unit by name (PGM-FI Main Relay 1, Throttle Actuator Control Module Relay, etc.) and tells you exactly which box they live in. If you’ve ever replaced a starter when it was just the Starter Cut Relay 1 in the auxiliary relay holder, you know how much this matters.

Why OEM Beats Aftermarket for Electrical Work

Aftermarket electrical schematics are often redrawn from memory or scanned from an earlier model year. I’ve seen wiring colors flipped, relay numbers wrong, and connector pinouts that belong to a completely different car. This manual came from Honda’s own print run for the 2007 RL. That means the wire colors, connector shapes, and relay assignments match what you’ll actually see under the dash. If you want to troubleshoot without creating new electrical problems, stick with factory documentation.

Real-World Use Case: Keyless Entry Module Diagnosis

A customer comes in with a 2007 RL that won’t lock or unlock with the remote. The aftermarket manual says “check the relay under the dash.” That’s useless. With this OEM schematic, you find the Keyless Answer Back Buzzer behind the middle of the rear bumper, then follow the wiring back to the control unit. You check the power feed at the driver’s under-dash fuse/relay box—component (20) is the Accessory Power Socket Relay, not what you need. The RL-specific wiring diagrams in this manual show the exact path. Pair it with the 2007 Acura RL Engine Performance Advanced Diagnostics”>2007 Acura RL Engine Performance Advanced Diagnostics manual for drivability electrical issues. And for basic operation, the Acura RL 2007 User Manual”>Acura RL 2007 User Manual covers the controls.

3 Reasons to Choose This Factory Manual

1. Verified component locations – Every relay, fuse, and buzzer is listed with figure references, not generic “under dash” guesses.
2. Voltage drop specifications – The schematic includes factory tolerances for signal circuits; no more wondering if 0.3V is acceptable.
3. Original print quality – Scanned from factory press, not a third-party photocopy that loses wire color labels.

FAQ – Common Questions About This Manual

Does this manual include wiring diagrams for the SH-AWD system?

Yes. The SH-AWD relay location is listed behind the rear seat, and the schematic covers the full SH-AWD electrical circuit, including the control unit connections. You won’t find that in a generic OEM manual—most aftermarket books skip it entirely.

What format is the manual in?

PDF, factory scan, 215 pages.

Can I print the diagrams?

Yes, the PDF is printable. I keep a laminated copy of the relay location table on my toolbox.

How does this manual compare to the Honda official service manual?

This is the electrical schematic volume only. It’s part of the official service manual set, focusing exclusively on electrical component locations, wiring diagrams, and connector pinouts. It does not include engine mechanical or body repair sections.
