Magsafe L connector disassemble. Replace the connector.

I have three 60w magsafe 1 power adapters. Two of them are fully original (including the cables) and one has a non original wire wit L connector replaced. It’s a well known fact that those replacement cables with L connectors do not work properly, the charging indicator is always green (even when the battery is being charged) and the overcharge protection doesn’t work. But on the other hand, the quality of the unoriginal replacement wire is a hundred times better than the Apple original, because apple’s wires crack very fast. Mine actually cracked like a year after I bought it new from one of those apple shops.

So I want to disassemble the original Apple L connector and solder it to the unoriginal cable. I don’t mind cutting off the replacement L connector, as it is of no use for me, because when I use it with my Macbook pro 13” late 2011, the battery gets hot, and when I used it with my Macbook white mid 2009, the battery swelled and now when I use that MB 2009 with the unoriginal cable, with no battery, it won’t even turn on (it does turn on when used with fully original power adapter).

So… disassemble an original magsafe L connectror and solder it to another wire. How do I do that? In fact the problem is more about disassembling the L connector, because I do know how to solder things.
