Well I got everything installed, and was able to get vin from CIC, but now have 2 problems. 1 is no sound, get message at start up from CIC "no tones" and second is CIC won't code. Already chaged VO build date to #0910 and option $609. When I go to code CIC I get an error.

Your MOST loop (green/black fiber) is open. Either you didn't plug the fiber into the CIC or you disconnected somewhere else

I put in emulator harness and noticed it did come with 2 wires that go to the top right side, are those the fiber? And if so, when you say loop tie them together ?

When all the fiber connections are in, its a closed loop forming the MOST bus. One side is transmit and one receive. If any one module on the MOST bus is unplugged, you will get the error that you did.

You need to plug in the green and black connectors where you highlighted

Emulator harness doesn't carry does cables through the harness, is there any way I can extend them to reach the CIC ?

You remove them from the stock harness, and patch them directly, should look like this in the quad lock connector

Perfect, thanks.

No luck, put in the MOST bus cables in back of harness and still get same message. "No Acoustic Tones" and same error when trying to code CIC in NCS. I'm just about ready to grab a hammer and beat the thing to death.

Are you sure you don't have them reversed?
