Hi guys and girls hope we all had a good Xmas! first time poster and have run into an issue obviously as I’m here, I’ve bought an installed an aftermarket dash camera from Ali express camera is good quality the issue is I believe the last part of puzzle is installing the connections into the main harness for the multimedia set up however I haven’t a clue where the wires themselves would go. from my understanding and looking at the ends of the cables they slot stright into the back of the harness so that’s easy it’s just finding out where in the harness they go? the kit came with zero fitting instructions, so I’m just sorta winging it here have attached pictures for reference thank you in advance!
