Any body figure out this wire on my MMCS there is a 5 pin connector in my Wiring diagram it is Connector C-13 on the schematic the pins are 21 -25 pin 25 is a purple or violet wire and I can't find where it goes to in the circuit diagrams. I have powered up my MMCS on the work bench and connected speakers I believe it senses if an amp is connected but just speakers on the connections work fine. So the gps know where it is all functions work except enviormental because can bus is not connected to the other can boxs.
