I purchased one of these units last summer and need some clarification about the two 'extra' wires coming from it.

The twin connector obviously goes into the main board plug that the standard smoke unit connects to (basically the power feed for the heater circuit in the smoke unit) and I am guessing that the two new leads have to connect into the gear box circuits somewhere to respond to variations in power feed to the drive motors to sync the air pump on the smoke unit.

My puzzle is where the best place is to make this second connection for the smoke unit blower? Choosing either the left or right drive motor would be simple, but not truly proportional unless driving straight. Depending on the motor chosen, a turn in one direction would produce nothing from the smoke unit, or full smoke going in the other direction.

It's getting late here and I am not certain this makes much sense, but if somebody can point me in the right direction, it would be greatly appreciated.

Hi Dave  There should be 4 extra wires that connect to the motors, either direct to the motors or to the motor conections on the board the unit plugs into the board the same way the old units did.  See photo of smoke unit the extra wires are on the left red and black a red and black go to each motor its this signal that increases the speed of the smoke unit motor.

Well Pete...you are absolutely right!!!

It must have been a lot longer day than I thought yesterday! There are two pairs of green and black leads on my unit and I don't know how the heck I missed that fact. I was scavenging sets of wires from several dead smoke units earlier in the week and my brain must have overloaded.

Thanks for the gentle nudge back to reality.

Best regards,

David

Here is a nice drawing someone made if there is still some confusion!

Thanks for the photo.

I've copied it into my hardcopy files for reference. I gave up on the mental notes to myself...too risky.

Oh ya, even if I have done it ten times, I want to double check it!
