Hi

For the speaker, depends on how you plan on using it.

If the radio will not have an internal speaker, then wire up to pins 3 and 4.

If the radio will have an internal speaker, then you need to wire up the jack as in the drawing that I posted. Then when you plug in external headphones or speakers, it will shut off the internal speaker.

I realized I should have put my understanding down along with the ask for help. Attached is a drawing I found that seems to represent our EP sockets included in the kit. My understanding is that, for both mic and head phones, Pin 1 would go to ground (black wire), and the brown wire would have to be split out to connect to both pins 2 and 5, at least on the headphones (stereo), not sure about on the mic though. For reference, I will be using?

Does this sound about right?

Thinking I fully understood the wiring of the BX and then having buggered it up more than once, I ask the collective for instructions for wiring up the two EP jack sockets. I have the link from last week??but again would like some further guidance to make sure I fully understand before firing up the soldering iron as I don't think my board can take another wiring muckup.
