Thanks for the information, Rickie..... I could probably use the universal 2d (presently disconnected) on the trolling motor and get by with 2 "y" connectors, but it would be a "Rube" arrangement as MonteSS says and would have an undesired tail hanging from my Terrova head. Was just looking for a way to get better DI from some of the extra pieces I have laying around. Guess I can live with DI from SI for now.
