Pretty sure it can be done but you need a wiring diagram for the radio pinout and the mic. Best leave it to a CB service shop.

google search,took me 5 seconds to find it.

Find your radio on this page and then look at the wiring diagrams

They are bother a simple 4 pin wire setup. Follow this and you will be good to go. 1 - GROUND SHIELD - BLACK
2 - AUDIO - WHITE / YELLOW
3 - TX - RED
4 - RX - BLUE

have you checked out cbtricks.com

HR2510 is very close to the same radio. Email me if you need the 2510 diagram. [email protected]

For a Turner +3 it is 1/shield 2/white 3/black 4/red.For an Astatic 4 wire it's as follows 1/shield 2/white 3/red 4/black ; for a 6 wire it is 1/shield&blue 2/white 3/red 4/black - yellow no connection . Good luck....Dan
