Bel RX65 Pro Series, need an extension - RJ11 or RJ12?

[armoredsaint]

I wanted to mount it at the top of my windshield and run an extension along the A-pillars.

Do I need a RJ11 or RJ12 cord and coupler for my Smartcord?

I've used RJ12 for my Escort 9500ix, but Bel chat support said to use RJ11? Does it matter?

I thought I read before to use RJ12 or it won't function correctly?

I believe a four conductor 11. Confirm PIN to PIN compatibility in your selection, though.
