Black - Negative/Ground to any convenient ground point but NOT the radio case
Yellow - Audio Output. Locate the audio wire on mic socket and solder wire to that pin. Original wire stays in place
Brown - Locate RX pin and remove the wire. Join this to brown wire and insulate
Green - Locate and remove wire from TX pin and solder to green wire and insulate
Blue - Solder blue wire directly to empty TX puin on mic socket
white - This wire allows bleep to be switched on/off. Connect to ground via convenient switch. On = white earthed, off = white not earthed
Bandit Type - RED, BLACK, BLUE, GREEN/YELLOW, ORANGE
Red - Connect to +12v
Black - Connect to ground but NOT cb case
Blue - Solder this wire directly to the audio pin on the mic socket
Green/Yellow - If there is NO yellow wire then solder the green wire to the TX pin on the mic socket. If there IS a yellow wire then remove the TX
wire from mic socket, connect it to the yellow wire and insulate it. Solder the Green pin to the TX pin on mic socket.
Orange - On units that produce the tone at the end of transmission (normal) ground this wire to turn it off. On bleeps with the tone at the beginning
of TX grounding the orange will prevent the tone being sent unless mic is keyed twice in quick succession
On many radio's the bleep will be heard through the CB speaker. To rectify this you will need to wire in a relay to switch the
speaker off during TX.
These can be obtained from most electonic suppliers, ie. Maplins,Rapid or RS.
