The 21 AWG AirLok hookup wire would be perfect for that application. Can you upload a photo or indicate the make/model of the DC connector? Is it the same type of connector at both ends?

I suggest building the DC umbilical with 2 foot wires, which will shorten a bit after they are gently twisted together with a lazy twist rate to form a bundle with a usable bend radius.

It's a hirose rm-w.

  Make sure to add more heat shrink for strain relief where the wiring is secured to the connector.

    Just ordered the wire. I will wait to it comes to order the connectors as I am not sure what size cable clamp to buy. I need to see what the diameter of the 10 wires and some shrink tubing come out to.
    
    I appreciate all the advise.

      Ask myself or Chris of VH Audio for any further advice. Maybe Chris can estimate the diameter of the 10-conductor bundle, and a particular size/type of heat shrink to choose. I recommend the Techflex Clean Cut braided sleeving he carries, since it is easy to work with, and provides excellent protection for the purpose.

        Ok. Chatted back and forth with Chris a little and ordered everything up. I will report back when it showed up. Mouser is not always the quickest getting to me.

        I'll keep an eye out for the report.
        
        Cheers, Duster
