I have several old style Connex Echo boards I would like to use on four pin cobra's and such. Does, anyone know how these hookup. Or mybe direct me to some instructions on how to install them. I use to know how. But, have forgoten how and can't find my install Info. These have Red, Black which I'm sure are pwr and grd . There are also four other's two are shields and two are white. Any info would be great! THanks Fella's!!

Not for sure if this is the correct one but hopefully it will help you in locating where your wires would go.

THanks SmokinJoe, That's It!!! That's what I needed!!

any chance anyone knows what the purpose of that bottom left socket is for, i have an old connex with it and three wires , (orange, red, brown) coming off it. the brown goes to the am/fm/pa selector, the other two go to the main pcb. There is also a Yellow wire on the audio in and out both. one goes again to the band select. the other to the power switch. I would like to remove the board temporarily. but not sure what I am unhooking on these.

The EPTOSSB50B Echo board is made by Ranger and is used in lots radios.

J1 = Mic output
J2 = Mic input
J3 = to Echo/Time pots
J4 = Power B+ 8vdc
