Is that a factory smoke unit or a Super Chuffer?
Thank you Pres. its the original semi smart smoke unit with the 8 ohm resistor replaced by a 22 ohm, on board circuitry bypassed, and the resistor wired directly to the R2LC.
The 4 lobe cam actuates the micro switch wired to a DPDT reed relay which drives the fan motor and chuff in on the R2LC.
