3M Scotchloks, is my love so wrong?
In October I promised to eventually discuss the 3M Scotchlok IDC connectors I used to tap into Gizmo’s engine gauge wires in order to install an Actisense EMU-1 Engine Monitoring Unit. Given that two experienced commenters already strongly dismissed these connectors for boat use, I did more research and testing. Tentative conclusion: While 3M does indeed state that Scotchloks like those tiny UY butt connectors above are meant only for 22-26 gauge solid copper conducter wires, they still seem like the fastest, surest way I’ve seen to splice the fine gauge stranded wires we often deal with afloat. Could it just be a mistake that’s kept a lot of useful Scotchlok models out of 3M’s limited marine line, or did I miss some major difference?
