Frequently Asked Questions - 70-5514 Metra

What vehicles is the Metra 70-5514 compatible with?

The Metra 70-5514 is designed for select GM, Chrysler, and other vehicles. Check Metra's online fit guide or your vehicle's specific model year for compatibility.

How do I identify the correct wire connections?

The harness uses standard aftermarket color codes: yellow (battery), red (ignition), black (ground), and paired speaker wires. Always verify with a multimeter before connecting.

Can I use this harness for a double-DIN radio installation?

Yes, the 70-5514 works with most single-DIN and double-DIN aftermarket radios as long as the vehicle connector matches.

Does this harness include a reverse trigger wire?

No, the 70-5514 does not include a dedicated reverse trigger wire. If needed, you must tap into the vehicle's reverse light circuit separately.

What should I do if a wire gets damaged?

The harness is not repairable. If a wire is damaged, replace the entire harness to ensure safe and reliable connections.

Can I use this harness for a 24V system?

No, the harness is rated for 12V DC only. Using it on a 24V system could cause damage or fire.
