Hello!
My first post on this forum. I am getting ready to install a new stereo in my 05 Crossfire Limited Roadster. I disconnected the wiring harness and antenna from the back of the factory unit. There is a second black wire as well. What is the wire I disconnected next to the harness? It is a lot smaller than the antenna wire. This is throwing me for a loop. Not sure if it is part of GPS or if it will be used in the new installation.
Thanks,
William

 

gps ( assuming you are removing a NAV unit )

 

Thanks for the quick response! Installing a Kenwood, so I assume I would not use this wire and just tuck back in the console? Seems like everything else is straight forward, just got this vehicle.
Thanks

Did you get the Kenwood wire harness adapter?

 

I got the correct Metra harness that plugs into the factory Nav Crossfire radio. It has 4 rca plugs for the speakers along with the color coded wires. Reading everything on the forum, it looks like I will be wiring the red to yellow and yellow to red due to Chrysler's specs. The Kenwood radio has its own connector in the back so should be OK. I am also installing a modulator for the satellite radio. Any other advice would be great!
Thanks@

 

I have some advice: Do not use the RCA outputs. The factory amp was designed to be driven at speaker level; 4V RCA outputs seem to work better than 2V outputs, but the two cars I modded, I found much better audio by using speaker outputs.

Also, do the four channel mod while you are at it, you will thank yourself (and me) later.

Sounds like you bought the Metra Harness 70-1786 (RCA plugs). You won't need to swap the Red & Yellow wires. That only happens if you bought Metra Harness 70-1784 (w/o RCA plugs). The 1784 harness is for VW & Audi applications, but can be used on M-B & Crossfire applications if the Red & Yellow wires are swapped. The 1786 harness is an update and it is no longer required to swap the wire colors on M-B & Crossfire applications.

You probably ought to review the attached DIY from Forum Member GregWork. His DIY write-up was one of the most straight-forward I came across regarding hooking up an after-market stereo to the Crossfire. (Note: Not sure what differences exist between the Infinity unit with or without NAV.) The Scosche VW01B wiring harness is identical to the Metra 70-1784 - both have no RCA connectors. Per pizzaguy, these wire harnesses enable you to direct-wire the speakers in the Crossfire.
