Here's a tip for the frst time swappers who aren't down for a full set of new lamps / rewire. I did this on my Skateball and it worked too well not to share.
Assuming a working machine as your staring point:
Remove and Label all Coils from the mechs.
Remove the Switches from the mechs, too and then Remove Mechs for rebuild and to locate and mark on the new PF..
Remove the main solder points for the Lighting GI/Control (Pops too) and Label them.
Remove all Harness Anchors and remove all Braid Staples.
Once everything is ready to lift free from the back of the PF. Take a section of Wire Fencing (I use 2" x 4" Box Fencing) and cut it to the size of a PF.
Lay the Fencing over the top of the wiring, pull the coils through the fencing (to keep the weight off the harness) and Zip / Twist Tie the ever loving shit outta the entire harness. You really can't use too many ties on your first go around. You can also pull switches through as needed to keep things clean.
Lift and transfer to the new PF. Locate all of your lamps and anchor points and land them right through the fencing. Clip the ties off as you go.
Real easy way to overcome the intimidation factor that comes with removing the entire harness / replacing all of the braid and lamps.
As for cleaning the harness. I usually do it on the old machine before I do the transfer. Just clip 3-4 Zip ties at a time and clean with rags then re-zip and move to the next section.
