About the Metra 70-6512 Amp Bypass Harness
The Metra 70-6512 harness enables you to install a new car stereo in your Ram truck. It uses a "jumper" to bypass the factory Infinity amplifier, which means you don't have to run new speaker wire from your new radio to your car's speakers — this saves you a lot of time on the installation, so you can start enjoying your music sooner.
Since you didn't have to cut off your car's original radio connector, it's easier to put the factory radio back in when you sell your vehicle or return it at the end of the lease. Just plug the factory radio back in and keep the aftermarket stereo. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this harness is compatible with your vehicle. Warranty: 1 year.
Installation Note: In 2004, Dodge offered two different amplifiers for different trim packages. The 70-6512 harness works with the SRT10 trim package without the hands-free calling option. If you're not sure, look at your rear-view mirror — if you don't see an icon of a telephone on it, this harness will work.
