John, I twisted them together very tight and user the longest lead to attach to the board. Naturally due to everything being tight I could not use the MTH wicking. I used the Lionel rope style wicking and both heaters pushed down on the wicking enough to make good contact and great smoke. I had this running for over a year then sold the engine to Matt Flanagan when I got word on a Legacy version in the works. Matt kept it for a while and moved it down the road.
JDADDY, smoke fan motors need to be run. Sitting for a year will make a few sing.
