They-Box Controller comes prewired. There are three cables coming from the box. One has a cigarette lighter plug. That is connected to your power supply. If you don’t need the cigarette lighter plug, then simply cut it off.

The molded black plug with the red/black wires is connected to the matching plug on the antenna. We have provided pig tail connectors to help with the wiring.

The third cable coming out of the controller has a three conductor 1/8 inch plug. That is a standard stereo plug. That plugs into the ACC Jack on the back of your FT-857 or FT-897. In your instructions, it is likely labeled number 4. Think of the switch in the control box as having an extra set of contacts that close when the switch is rocked up or down. Each time you rock the switch the motor is turned on and the transceiver will transmit a carrier. After the switch is released, the transceiver will continue to transmit for a few seconds giving you extra time to observe the built-in SWR meter. When rocking the switch, tune for an SWR of less than 2:1 and release the switch. The antenna is tuned.

The light on the control box will illuminate when the antenna’s coil is fully extended or fully retracted. The light may also blink when the antenna’s motor is started. This is normal and expected. The lens on the light assembly may be red or green. It does not matter.
