Metra radio wiring harness 70-7552

Technical details

When replacing or connecting a radio, the wiring connection is one of the details that can determine whether the job moves ahead smoothly. The Metra 70-7552 is a radio wiring harness listed for Nissan vehicles from 2007 onward.

Its stated role is straightforward: it plugs into the car harness at the radio. The listing does not provide connector dimensions, wire colours, installation instructions, or a detailed vehicle fitment chart, so treat the Nissan year range as a starting point rather than proof that it suits every vehicle in that range.

Getting the most from it

This harness is intended for the connection at the radio end, not as a complete radio-installation kit. Before choosing it, match the year and model of your Nissan against the vehicle-specific fitment information available to you, and compare the connector with the factory harness where possible. The product details provided do not identify particular Nissan models or trims.

It’s a good fit if you need a harness for the radio connection and your vehicle is confirmed as compatible. If you are looking for a complete installation package, or need confirmation for a specific trim, the listing alone does not establish that those requirements are covered.

Usage tips

Keep the factory wiring harness intact where possible and work from the connection at the radio, which is the location identified for this part. A practical check before starting is to compare the vehicle-side plug with the harness connection and confirm the vehicle’s year and model against a reliable fitment listing. If the connectors do not match, stop rather than forcing the connection.

The available description does not explain wiring colours, provide a wiring diagram, or state whether other installation parts are included. Plan to identify any additional parts or installation guidance your radio setup requires, this harness should not be assumed to supply them.

Three specific questions

What does the harness connect to? It plugs into the car harness at the radio, according to the product description.

Which vehicles is it listed for? The product name specifies Nissan 07-Up. Specific models and trims are not identified in the supplied details, so confirm fitment for your vehicle before buying.

Does it include a wiring diagram or other installation parts? The available information does not say. If you need a diagram or a broader installation kit, verify those requirements separately.

Before you buy

This is a focused part for the radio-side harness connection, rather than a general-purpose bundle with documented accessories. That makes it worth considering when you already know the required connection and have confirmed vehicle fitment. It may not suit you if you need a clearly documented, model-by-model compatibility list or installation instructions in the product details. The key decision is whether the 2007-onward Nissan listing matches your exact vehicle, the description does not provide enough detail to settle that question on its own.
