The Metra Electronics 70-7552 wiring harness is presented as a compact, lightweight adapter for select Nissan (2007+) and Subaru (2008–2015) models, with IDC connectors, color-coded wires, and a typical install time of 15–30 minutes. It delivers solid audio pass-through, requires possible dash kits or antenna adapters, and measures roughly 6–8 inches of usable lead length; is it the simplest swap or does the project need extra parts?
Key Takeaways
- Compact, lightweight IDC harness enables factory-to-aftermarket radio swaps for select Nissan (2007+) and Subaru (2008–2015) models.
- Direct IDC connectors with clear color coding provide quick, reliable four-speaker power connections and minimal soldering.
- Installers report straightforward installs: 15–30 minutes bench time plus 10–20 minutes for dash removal.

- Manufacturer offers 1-year limited warranty, 7-day tech support, and positive user ratings (approx. 4.5/5).
Product Features and Compatibility
While the harness is compact and lightweight, it is engineered to simplify factory-to-aftermarket radio swaps for specific Nissan and Subaru vehicles.
It offers direct IDC connectors, four-speaker power, and clear wiring color coding, aiding quick identification.
What vehicles are supported? Select Nissan models (2007-up) and Subaru models (2008–2015).
Measurements: 8 x 5 x 1 inches, weight 0.05 lb (0.8 oz).
Practical considerations: dash kit, antenna adapter, or interface adapter may be needed.
Warranty: 1 year limited.
How reliable is fitment? Vehicle compatibility is strong when matched to model years, but verify trim-specific connectors first.
Installation Experience and Performance
Because it connects directly to factory harnesses using IDC connectors, the Metra 70-7552 tends to make installations quicker and more predictable for compatible Nissan (2007‑up) and Subaru (2008–2015) models.
Installers report straightforward fits, color-coded leads, and firm connectors; typical bench time is 15–30 minutes, dash removal adds 10–20 minutes.
Installers praise the straightforward fit, color‑coded leads, and firm connectors; bench time 15–30 minutes, dash removal 10–20.
What are practical installation tips? Use a trim tool, verify 12V constant and switched with a multimeter (12.6–13.8V), and secure ground within 2–4 inches of chassis.
User experiences note solid audio performance, reliable connections, and occasional need for a dash kit or antenna adapter.
- Fast plug-and-play IDC
- Clear color coding
- Minimal soldering required

Frequently Asked Questions
Does It Retain Factory Steering Wheel Control Functions?
No — it does not retain factory steering wheel control functions by itself. The harness provides steering wheel compatibility only when used with a separate special interface adapter that translates the vehicle’s control signals to the aftermarket radio.
Is There Any Noise or Interference With Factory Amplifiers?
No significant noise or interference is typically reported; users note adequate noise reduction and solid amplifier compatibility when properly installed, though additional grounding or interface adapters may be recommended to avoid rare hiss or grounding-loop issues.
Can It Be Used With Aftermarket Backup Cameras?
Yes, it can: coincidence suggests aftermarket compatibility often depends on head unit inputs, so the harness itself doesn’t provide camera installation video signals, yet it facilitates power and speaker wiring while camera integration requires the radio’s camera input or adapter.
Is the Harness Soldered or Uses Crimp Connectors?
The harness uses crimping methods rather than soldering techniques; connectors are IDC/crimp-style for direct plug-in installation, avoiding factory wire cutting. Users may still opt to solder joints for added reliability if preferred.
Are Replacement Adapters Available Separately?
Yes — ironically, replacement parts do exist separately; third parties and OEM sources commonly offer adapter compatibility options. Buyers should verify connectors and vehicle fitment before purchase to confirm proper function and avoid additional adapters.
Conclusion
Conclusion:
The 70-7552 is a compact, reliable wiring harness: direct IDC connectors, color-coded leads, 15–30 minute install time, 1-year warranty. Think of one customer’s Subaru where the harness fit like a bridge bolt, restoring sound in under 20 minutes — a clear visual of quick, secure connectivity. Who should buy it? Owners of compatible Nissan/Subaru models needing a straightforward radio swap. Verify vehicle year and consider dash kits or antenna adapters before purchase.
