Powering 4 different things & B/DSC connector.

[Fiddybux]

Right, I've got my TRF501x which, as any car, needs the speedo and servo connected to the reciever (in this case an RX-311).

The spare aux socket I have used to power a fan to keep things cooler.

Now I want to power a Personal Transponder in the same car, but I have no spare connections left. What gives?

Will the B/DSC port provide power? Or do I need to split some leads somewhere to power, for example, my fan and PT at the same time?

Here's the connector I mean:-



Thanks all.
