Has anyone installed ESU LokPilot decoders into InterMountain FT diesels? The drop-in Digitrax boards leave a little to be desired, especially when trying to consist an FT ABBA set. I'd rather use LokPilot decoders hard-wired in. Just have to figure out the weird stock motherboard board interface and add a resistor to the headlights. But if someone already has done performed the procedure, no reason to reinvent the wheel. Thx.
