I've done a ton of them [15 airplanes to date] and to post my time would be mis-leading to use as a guide for others who have yet to experience the pleasure.
However, I'll make an exception in your case because you are such an exceptional guy. When I tackle a conduit installation I prefer to arrive after removal of the seats and center floor sections; then it takes me 1-1/2 to 2 days usually. If there are no "issues" it goes quickly. If an airplane has suffered the rigors of mortis and I have to correct things, that's obviously extra time. Good advise, get someone who is familar or buy the manual. The manual will save tons of time, and it's brilliantly written

Remember the conduit installation requires lots of post-install adjustments. If the installer isn't familar you will pay for the learning curve or may not even get it done correctly; I've seen that too; right?
