I have been trying to install a keyless entry, https://www.amazon.com/gp/product/B01HB5M5R2/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 and followed the info I found from this forum to splice into wires 9 and 10 in the ECU harness, violet and beige. The locking works but unlocking does not. I am trying to figure out what I did wrong, I am thinking either its the box I bought or I spliced the wrong wires. Any help with this would be appreciated!

It could be worthwhile to check the door lock and unlock relays.
These appear to be in the Instrumemt Panel Junction Block mounted on the bottom of the Main Body ECU. I think this location is also referenced as the under instrumnet panel fuse location. My diagram shows the relays located next to the 20 Amp "DOOR R/L" fuse, but this may be wrong.
One relay is used to lock the doors, and the other unlocks the doors. You can check their operation by swapping the relays.

Thanks for the response!
So just so Im clear your talking about the fuse box under the hood and not the fuse box under the steering wheel? Because I do not see any relays near the fuse box under near the pedals, unless they’re covered or something. Just for clarification I have attached a pic of where I spliced the wires

I'm just working from the wiring diagram and drawings in the service manual.
I have attached these for you. Hopefully these will help.

I just went out to the garage and checked on My Yaris. It sounds like the relays are either behind the fuse panel under the dashboard, or inside the body ECU.
The unlock signal should be an earth on pin 10 of connector F82.
