my newest plane Dynam F6F Hellcat my first with retracts I found I have no way to connect both retracts to the receiver I am figuring there is a Y plug ? was given a 5 wire harness 2 go to the lights but the other 3 have no use? anyone can educate my I would appreciate it thanks

I would assume a standard servo Y cable should do the trick, unless Dynam have some form of proprietary plug and cable which one would think they should include. My last electric retracts used a standard Y cable plugged into Ch. 5.

But as this is quite an old post I would hope that a resolution has been found by now.

Yup, you're on the right track with the Y plug idea. That's usually the way to connect both retracts to your receiver if you don't have separate channels for each. As for the extra wires in the harness, they might be for additional functions like gear doors or maybe even a brake if your retracts have that feature.
