[arm-allstar] Please help me validate this is the correct CDM750 to DMK URI cable

[Robert Prybyzerski]

That looks mostly correct except for 15-16 internal speaker.  Don’t jump those 2 together.  

You also may need to apply 12v for ignition sense on pin 10 of the CDM. 

I have examples of how I made my connections on www.qsl.net/w2ymm/irlp_cable_moto.html
