In my case there was insluating foam that was sprayed around the windows, making the depth of the opening for the sensors very limited. It was hard enough to try to stuff the wire back in the hole, let alone deal with a resistor.upstatemike said:Even a recessed contact is installed with enough slack so it can be pulled out for service or replacement if needed. Why can't you just pop out the last contact, add a 1/4 watt resistor (which will fit in behind even 1/4 inch recessed conacts) and pop it back in? I can't picture where opening the walls comes into the picture.
Yes, this is one good suggestion! Another may be to just solder the wires and use shrink wrap over the entire assembly.upstatemike said:I think the connectors are the big challenge. Even b connentors take up too much space. For an EOL resistor I would probably solder the connections and insulate with a dab of silicone.
