New post still problems

I have written before about my E1H1-015A Nordyne. About the wiring problems with it.
Well I was finally able to get the heater control (sequencers and timers) re-wired.
Now the Elements will come on and after a few minutes they will turn off, (like they should).
The fan will not run at any time, just hummm.
The HVAC Tech has wires that when wired correctly have 24V going to the motor and 240V going to the R terminal on the control board. (Nordyne Part 624-5680).
I would like to completely remove this control box, and replace it with contactors. I have not been able to find a diagram for the T-stat and air side of this unit.
So I would like to know the following:
1. Take the wires on the R & RH Terminals to the Red wire from Transformer?
2. Connect the rest of the wires to their mates from T-stat?
3. Use wires from G and C wires to coil side of contactor?
4. Use wire from W on T-stat for a heat contactor? Black wire from bottom Sequencer?
5. Then sort out which 2 wires will give motor 240V for Air and 240V for Heat.
Maybe $21.00 something compared to $61.00 and a little more time to set up.
Have noticed several of your past posts always saying that fan is controlled by sequencer, I see that it gets 1/2 it voltage from there, but my diagrams all show Blower relay between sequencer and motor. Are drawings wrong??
Thank you in advance
