lever nuts for remote starter?

I am going to install an Avital 4103LX into a 2004 Subaru Outback. I've installed a couple remote starters in the past using the tap splice method, but I've recently discovered these wago lever nuts. I'm sure they can handle the current. And I think this would be a lot easier/cleaner than the splices... Don't need to solder and tape. The only thing I don't really like is that I'd have to completely cut the car's wires to use these. What do you guys think?

No way, unfortunately if you used tap slices and those connectors you'd be immediately dismissed from any decent shop either in the US or UK, absolutely useless in a moving, vibrating damp environment.

Totally agree with Howie...Maybe it would work in an old hot rod but in a modern car with sensitive electronics. NO WAY. Added resistance, increased risk of being stranded on the side of the road while your car burns down. It is a personal choice. You won't find support here for doing things the easy way. I always applaud anyone for thinking outside the box, but in this case the box exists for a reason. Apologies if I sound harsh, but the point needs to get across. To master and control electricity is perfection. *evil laugh*

Even the comment if I was interviewing you:- "I've installed a couple remote starters in the past using the tap splice method." Means I wouldn't employ you.
