Little dongles are pricey & I’ve got a couple of each end, figured it possible You’ll need a solder, wire strippers/cutters On the lightning side, you’ll find 6 wires RY, GR, & GY can be soldered together for grounding Red is right speaker Green is left speaker Silver or gold is your mic (You can cut this out if you don’t need it) Followed these 4 wires down to the female 3.5mm Marked their posts on the jack You can also plug in a male jack to test the rings with a polarity tester to know which is which & wire accordingly Soldered each tip to corresponding tabs Now the iPhone plugs into my aux I installed using [mention]Vansquish [/mention] how-to Two types of females I’ve ran into Lots of polarity testing, but fairly easy to figure out. I had all the tools so I saved about $20 & the cord is much longer The cheaper lightning cables will burn up pretty quick. I used the factory headphones for the lightning & aux extension I had for some selfie stick that I kept for the extendable handle lol Doing the life proof dongle next just to sharpen my soldering skills & I’ll take more pics to add of finished product. First one I did Hope that helps !
