Rick, Yes 90 feet is a long way. I’ve read some people have used bus wiring with DCS and get away with it. I don’t know.
Michael, yes your drawing is exactly what I mean. I think some double sided tape hold seemingly forever and some doesn’t. Some of the nylon cable clamps I looked at came with sticky back. What was out there years ago wasn’t very good. I ordered some of them thinking these may be better and some with a hole for a screw.
