I have just installed the AT-940 in my ts-940s .....I have all the wires in the right place but it does not work.....what I would like to know: is their a number 4 and 5 connector that should be hooked up and if so where might they be located in the radio.....the manual shows a number 4 & 5 connector hooked to the at-940 unit......Thank You....JT.....
