How to power on? Cant use power pads or keyboard

I am working on converting my old macbook into a SFF desktop to use for media and I need a way to turn it on without the keyboard. The keyboard is stuffed (It had coke spilled through it), the retention arm is broken to hold the cable in also, I tried soldering on another power button onto the power on pads with a resistor (cant remember what resistance I read somewhere) but it didn't work so I took the button I made off and now there is only 1 power on pad visible the other one is just gone and wont jump start with just a piece of wire like it did before. Does anyone know of another way that I can turn it on? Would a keyboard with a power button work?

Schematics show that pin5 (right to left) shorted to ground on keyboard connector of the logic board should allow you to simulate the on/off keyboard button.

However, on these schematics of A1342 I found some other mistakes before, therefore don't blame me if anything goes wrong =;)

No need to access the connector this model has power pads!

There are a few versions of this logic board so your pads maybe vertical but are in the same location. You need to do a momentary short across the pads. I would start there otherwise you'll need a replacement keyboard to replace your damaged one.

Depending on which pad you can short the good pad to ground as well thats if the sound pad is the one thats damaged.
