Now you can assembly the connector accessories. Tighten the plastic ring

of the 7-contact connector firmly in order to protect it hermetically.

When you use the ACOM2000S automatic antenna selector, before trim-

ming and soldering the second cable end, thread the hollow nut of the 8

contact connector oriented with the smaller diameter to the cable end.

Solder all 6 wires and the shield to mate directly by numbers to the 8 -

contact connector for the selector side as follows:
