I purchased a Speedway 12-circuit, 12 volt wiring harness to install in my 1950 Chevy half ton truck. The HOA won’t allow me to work on my truck in the driveway, so I’ll have to pay a shop to install it. How many hours should it take for a professional to install the harness?

Secondly, how long should it take a professional to remove the original 6 volt wiring harness?

Many thanks!
