This has been said many times and bears repeating. When you disassemble components take pictures, put fasteners in a marked bag or punch into cardboard in the pattern they were removed. If you disconnect wiring take a pic or draw a diagram. This will save hours of hassle, agony, time in the blazing sun, it may even promote world peace.
Do not rely on your memory over the course of a 2 day repair, unless it is much better than my middle aged one. I am going to have a cold glass of tea and a shower.
