Clearing Check Engine and Lighting Mishaps

Still new to all this. My old man let me order and install some Raptor lights (from 4Runner lifestyle) on our family's new 2021 4Runner. Then things fell apart into a series of mistakes

I watched the wrong install video which told me to plug the fuse tap into the engine fuse block, using slot EF2. EF2 uses a 7.5A fuse. The fuse tap came with a 15A fuse. I started up the car and it was errors everywhere! (TRAC, check engine light, take it to a dealership). But hey, the lights worked. My dad didn't find this funny.

I unplugged the fuse tap and replaced the 7.5A fuse. Started it back up and the errors were still there. Took it for a spin around the block and it still seems to drive the same.

I found the (right) 4Runner lifestyle install video which mentioned a different technique of pulling the wires into the cabin and using a spare 10A fuse port. Video is here: https://www.youtube.com/watch?v=psFKVid15Eg

This leaves me with two questions.

1. How do I reset the error status? I'm pretty sure everything is working alright. My old man scheduled a maintenance appointment at the dealership (I have to pay for), but I'm still in school and don't have a lot of money. Other places say you can disconnect the battery (which my dad isn't happy about) or to use an OBD2 reader.

2. Should I replace the 15A fuse in the tap with a 10A and plug it in as mentioned in the video, or is it ok to plug it in with a 15A? I'm kind of nervous about making the problem worse.

 

FWIW, I asked 4Runner lifestyle about question #2 and they just replied with "You actually leave that 15A and put a 10A in it as well and then it goes to a 10A port!"

 

Buy yourself a cheap OBD2 reader and clear the codes. If they come back, then you are in trouble and will be much poorer.
