Frequently Asked Questions - 99-8164G Metra

Which vehicles is the Metra 99-8164G compatible with?

The Metra 99-8164G is designed for select Chrysler, Dodge, Jeep, and Ram vehicles from model years 2004 to 2013. Always double-check your vehicle's specific make and model before purchase.

Does this wiring harness include instructions?

Yes, the kit includes a user manual with wiring diagrams and installation steps. You can also download the manual from the manufacturer's website.

Can I install this without professional help?

Yes, it is designed for DIY installation. However, basic knowledge of car audio wiring and proper tools (wire strippers, crimpers) are recommended. Disconnect the battery before starting.

What are the wire color codes used?

The harness uses standard aftermarket colors: yellow (constant 12V), red (switched 12V), black (ground), and speaker wires with pairs (white, gray, green, purple) for front/rear left/right.

Does this harness retain steering wheel controls?

No, the 99-8164G is a basic wiring harness and does not retain steering wheel controls. An additional adapter (like Metra Axxess) is needed for that feature.

What is the length of the harness?

The harness is approximately 12 inches (30 cm) long, which provides enough slack for most DIN and double-DIN aftermarket stereos.

Is this harness compatible with amplified systems?

It works with most factory non-amplified systems. For amplified systems, you may need an additional interface to bypass the factory amp.

How do I connect the wires?

You can either solder and heat-shrink for a permanent connection or use crimp connectors with a proper tool. Match wire colors from the harness to your aftermarket stereo's wiring.

Can I use this harness with a different brand stereo?

Yes, it works with any aftermarket stereo that has standard ISO connectors. Just match the wire colors accordingly.

What should I do if the harness does not fit?

First, verify your vehicle's compatibility. If it fits but connections seem off, check your wiring diagram. If the connectors are different, you may have the wrong harness. Contact Metra support for assistance.
