So just to close the loop. Other than the smoke unit itself the existing board was not providing any other functional support, since the engine headlight is wired to the cruise commander. I cut the board to remove the traces and replaced the two original smoke resistors which I tested out at about 15 ohms each with one 27 ohm resistor, grounding to the chasis and wired to the ERR pinout for the smoke unit. Smokes like crazy now. Thanks for all the good tips. I always appreciate the support from this group.
thanks
