All manual to mostly all automatic features conversion question - Toyota Yaris Forums

Hello Everyone,

I am about to wire up my power windows. I bought a power window kit from A1electric, SPAL motors and SPAL 3 switch kit. Installing most of the hardware has been quite easy, figuring out wiring has been a bit more difficult, mostly because I do not want to blow a fuse and I also would like to prevent any future accidents, such as a wire coming lose or something worse happening. But the threads on this forum have helped a lot. To the actual questions…
The grey cable for the illumination will be connected to the brown wire from the dimmer rheostat. It seems they are different gauge values, but I have not been able to take a better look. What is the general rule of thumb here? Can I still just tap to the brown, thinner looking wire, without worrying much? The diagram does not show it needs a fuse or give any suggestions.
For the red cable, which needs 12V and has a 25A fuse, the SPAL wiring diagram shows a relay to be optional part of the process. It would be simpler to tap into an “accessory on” wire, but I am not sure if the relay is a better solution. Similar question as above, does the difference in gauge matter in this application?

Other more general questions….
To tap into the cables, I am considering using T-taps, it seems there have been debates most favoring soldering as a much better job if done well. I am not sure of how well I could solder, but have bought lots of wires to practice on. Would it be ok/safe to use t-taps until I can get my soldering skills improved and redo the wiring in a cleaner way a couple of months later?
Also, what is the best way to add the 25A inline fuse to the 12V red cable coming from the switch kit to the relay/accessory power connection. Buy inline fuse holders? Or just add female spade terminals to the wire
I am not in a rush, so am willing to learn and gather more knowledge. Just a couple of days ago I was a bit scared about the process, but after reading a decent amount of threads I am much more confident about the installation.
