Default Wiring Harness Install- HELP!!

I'm trying to remove the wiring harness in my 78 Monte but I'm not sure the right steps or all of the steps I need to take to get the old harness out and put the new harness in. The new harness is a painless wiring 18 circuit GM keyed harness and seems pretty straight-forward on the directions. The biggest problem I have is around the firewall, getting to all the wiring and exactly what parts I need to remove before I can pull out the old harness without damaging the connectors that I will need for the new harness. I think I might have bitten off more than I can chew but it's too late to turn back now. Any and all comments/tips would be greatly appreciated!!!

I highly recommend marking each and every connector...use a peice of masking tape on each connection. And number it... Use a separate peice of paper to document each connection.and its corresponding number...

Most of all... Take ur time!

The wire harness is probably close to one of the first parts of the car in the assembly process so i think to remove it properly you would have to have most of the interior stripped out.
