The basics:
T104 is a mechanical on/off switch
T106 is a mechanical high/low switch
I already had a single speed pump with a T104, so I elected to save money instead of going digital and to add a T106.
The Wiring:
Old:
T104 line side (power into T104) wiring remains.
load side wiring (old T104 wires to pump motor) shall be de-installed.
New:
Load side (between T106 and pump motor)
Inside T106:
Terminal A: Green wire, routes to (C) common on pump motor.
Terminal 1: Black wire, routes to (H) high speed on pump motor.
Terminal 4: Red wire, routes to (L) low speed on pump motor.
Wire gauge is based on the amps used by the particular wire. A chart is here: http://www.intermatic.com/~/media/files ... glish.ashx
__________________________________________________________
Line side (power into the T106) is where the issues are for me.
I need two sources for power:
Switched on/off from my T104 to turn the pump on/off.
Constant power to keep my T106 clock going.
There are directions online, but they are far from clear to me.

They say: "If you are bringing power into your T106 timer from a T104 timer, then take your white timer motor wires to the line side of the T104 timer so that the clock motor on your T106 timer will keep moving even if the T104 shuts off."
Whatever that means.
The wires that power the T106 clock mechanism are brown, and attach to Terminals A & 2 of the T106.
The wires that power the T104 clock mechanism are white, and they attach to terminals 1 & 3 of the T104, which are the line load side (constant power.)
___________________________________________________________
The rest of this contains guesswork. This is where I need help.
T106 comes with a jumper between Terminals 2 and 3.
My guess is that Terminal 2 is constant power and Terminal 3 is switched power, and I need to remove this jumper. Am I correct?
Switched power (line side into T106):
At the load side (output) of the T104:
Terminals 2 & 4 have two yellow wires (each a 110V leg?)
And a common.
These supply switched on/off.
My guess is that T104 Terminals 2 & 4 should be wired to T106 Terminals A & 3.
Constant power:
I then should run a wire from Terminal 3 of the T104 (The line load constant power) to T106 Terminal 3.
Am I good, or am I missing something?
