1. Unpack the kit double checking that you have 10x 3.5mm mono plugs and 10x AllFlesh pcbs. Using clippers clip apart all 10 PCBs at the perforation marks and remove the remaining small tabs in the same way. (Note: I have not done that in my photo examples but this will help you in later steps to not damage your solder joints). Unscrew the mono plugs from their black plastic housings. You will need on hand safety glasses, a soldering iron, solder, clippers, and a file.
**Try not to exceed 700F/375C with your soldiering iron and use good soldering practices as leaving the iron in contact with the solder lugs for too long can ruin the plug internals.
