Nissan Repair: Door and Trunk Removal, pig tail, hollow trunk

Question
I have a 1992 Pontiac Grand Am SE V6 and soon i will be sanding down my car and painting it. but i want to do it in sections. so i plan on taking off certain things and paint them. so i want to take off my doors and trunk.
  
   i see the bolts to remove the doors, but there is that rubber tube between the body of the car and the door that houses all the wires that go from the body of the car to the door. how do i disconnect those wires and remove the door safely?
 
    and the trunk, i see the bolts to remove it off of the hinge thing, and i see how to remove the spoiler. but there is a device on it that opens, secures, and locks the trunk. it has a black wire leading from the inside of the trunk to the top of the trunk to the trunk opener. how do i disconnect that wire? i was just going to unscrew the entire device, but the wires is threaded into the tube that hold the trunk, (there are 2 parts of this tube, one on the left side and one on the right side that holds up the trunk and what not, only one side has the wire going through it). so how can i disconnect that and take off the trunk lid?

Thanks for the help!

Answer
As for your first question...you're just going to have to remove the door's interior, and remove that entire wiring harness...if you're lucky, you find a main pig tail to separate...if not, just start pulling everything off.  When your done, the harness has a gromet on the door jamb...either shove all the wires through it, or shove or pull the gromet out with the harness.

Ok...you said "but the wires is threaded into the tube that hold the trunk"...I think you are saying that the wires run within the tube.

Great...just remove all you can at the end, and slip/pull the wires through the hollow trunk support tube.

You got it...just reverse engineer this.

I have a question for you now…

Are you aware that painting at different temperatures, at different humidity, on different days...is going to give you different results?

Have you ever walked on a sidewalk that was poured when a development came in, but different sections look different--not uniform?  That's what different temperatures and humidity levels can do to your project.

I suggest you consider keeping the vehicle together so the overall flash time of the paint remains the same.
