the GC. Thread the heater/sensor lead(s) to the right side of the

instrument, through one of the keyhole wiring slots and into the P1 or

P2 detector on the actuator bracket.

Install the valve driver block

Slide the valve driver block down into the driver bracket until the drivers

plug into the connectors.

To remove drivers from the driver block, use a hex wrench to unscrew the
