I ask this for a future project I plan to set in motion soon.
Knowing that today's Legacy steam engines can swap tenders relatively easily, I would like to change the tender on one of the Legacy steamers, say the Legacy Berkshire tender Lionel did in 2009-2010, to have the same small IR sensor that is being used on the current Legacy steam engines.
I look on Lionel's website that the new Legacy steamers' sensors are 2-wire while the earlier ones are usually 3.
<< 3 Wire
<< 2 Wire
Has anyone tried to do this too? If so, please explain how it could be done. I know that engines and tenders and tenders with different drawbar couplings/ sensors don't work well with each other.
