Concert 2 to Symphony 3...K Bus???

[randall977]

Having a couple of problems with an RNS-E adapter which I inherited with a Symphony 3 off eBay. I'm in the last stage of upgarding from a Concert 2 to a Symphony 3. The adpater which connects to my old loom has two wires missing - one is 'K-Bus' and the other is 'DWA-GND'. Can I connect the 'DWA-GND' on the old loom to 'DWA' on Symphony? What can I connect the 'K-Bus' from the old loom to on the Symphony? I was planning to take out 'Can L' and 'Can H' to use the wires - they don't appear to be used...

The two snipped wires are ones I have added - ignore the glue on the connector!

Been scratching around on the web and it seems that;

K-Bus goes to +UB CDC
DWA-GND goes to DWA (car alarm)
Bose goes to Aux (earth)

I had already put Bose to Bose - which seemed logical - I shall swap it back!

Anyone had experience with this?
