I have a single one 24v/6V converter that I presume is for the Recoil thing like this. I wrote down what the label on the lower side say, as I will use velcro tape to hold it.
Wire and labels on say connect to Slew servo and slew servo reciever

this was the last one

The 5B wiring diagram I can see 24V/5V to input 2 . also on the picture I can see two wire on the recoil unit .
On my unit there was only one, the Input 1 to Audio.

Hope some one can help me out here.
