[Amps] Kenwood ts 870s used with linear

[John Irwin]

Hi dudes
 
 
I have a Kenwood TS870S
and do not have a linear but am building one.  My question is about the remote jack on the backof the Kenwood ts870s.  I am planning to use a 12vdc coaxial relay to switch antenna around the amplifier.  The manual shows  this jack on page 5  having  a internal switch using pins 2, 4and 5  and pin 7 which has source 12vdc at 10 amps.
 
Can I use the pin 7 output to ground to power the 12vdc relay ?
