Blew the pads off L4803 after reinserting the trackpad cable
I forgot to press the battery disconnect button prior to swapping the trackpad cable in a 2016 A1534. I noticed a little spark/sizzle/smoke come from the logic board sizzle as I was closing up the Macbook. Needless to say the keyboard and trackpad are no longer working. I took a close look at the logic board under a microscope and I found nothing but a nice big solder ball sitting between the pads of L4803 .
I’m not too familiar with board level repair but I’ve been reading a bit about it in light of this disaster and I figure since I have access to all of the tools required to attempt repairing it that I could give it a shot. I don’t see any traces leading to L4803, does anyone know where I would solder a jumper wire?

Is this a good question?
