I have tried to find something that would work and even thought that if I could invent one it would sell well.
What we've taken to is keeping everything organized in the shop in a drawer we built. We now document the pre-wire for plate color and the exact configuraton we need at trimout. This way the guys take what they need for that trimout on the day they are set to do it. That way they don't end up in every corner of the van destroyed because the air compressor got thrown on top of them.
I tried the Ziploc bag method but installers grab what they need and spill the contents into the bottom of a tub (did I mention that entire Xantech IR systems also reside in this tub underneath all the now loose plates and inserts... of course I discovered this AFTER running to a distributor to purchase a new one and deliver it to the crew).
I'm too busy to develop any better solution but if someone has a great idea... I'll bet its marketable.
