Yaesu FT-8800R Separation Cable Wiring

So you forgot to buy the separation cable for your FT-8800R and you’d really like to put the head unit on your dash while the body of the radio hides somewhere obscure, , or you’ve lost the little cable that comes with the radio so you can’t join them together. Good news: there is a solution to your troubles, and it’s pretty easy to come by, provided you have a crimper tool for camping telephone and ethernet cables.

You’ll need RJ-25 (6-pin) modular plugs and a six-conductor cable of sufficient length. I used Cat 3, but you could use Cat 5 just as easily. The wiring is incredibly easy, just ensure that you have the six conductors in the same order on both plugs. You’re essentially making a straight-through cable. To make life easy on myself, I use the 568A wiring spec and just leave off the brown and white/brown pair.

Trim the cable housing down, insert the conductors into the plug housing, ensure you have a snug fit, crimp the connector, and repeat on the other end, boom, you have a separation cable.
