[VHFcontesting] Setting up TE RF amp for use with a sequencer.

The TE manual gives some simple instruction for hard keying the amplifier but out an abundance of caution I want to verify my understanding of them before I start cutting wires and adding relays.

The DEMI sequencer gives a sequenced PTT ground to enable the amplifier.  The TE  instructions are to cut the internal  shorting wire between pins 5 & 6 and then connect the PTT ground to pin 2.

To enable the RF amplifier the TE instructions are:  1) Connect pin 5 & 6 then 2) connect pin 2 to PTT ground.

My interpretation of these instruction are:
I need to use the PTT ground to close a relay that connects pins 5 & 6 and then use an output from this relay to close another relay that connects the PTT ground to pin 2 on the amplifier.

Is this correct?
Is there a better way?
