I have a 99-01 911 with CDR-210 it comes with factory amp. I'm trying to locate what wire color the remote is. It's usually blue wire for aftermarket stereo. But don't know which color it is on factory.

Thanks

 

Nobody knows?

 

Here's a crude method using a multi-meter:
1. Ground the black lead.
2. Using the sharp end of the positive lead (usually the color red), shove it into various amp wires while another person turns the radio on and off. The multi-meter will display a very low voltage (typically 3 volts or amp turn-on leads) when you find the correct wire. To verify, assure the voltage reads zero again while your assistant turns the radio off.

What you really need is a wire layout. Email Rod from -- http://www.caraudioinnovations.com -- he could probably tell you in a heartbeat.

 

I found it thanks!
