The labor, as printed on the installation instructions, is 1.5 hours for the CB/Intercom & 1. 5 hours for the Entertainment Harness. I was told by Matt, of BRP, that the labor is based on junior tech times who've performed the install several times. If I recall, I took three evenings and most of a Saturday, but could probably have done it much faster with each time doing it, but haven't tried it again.
