Do yourself a favor and never use this type of splice on any type of wiring unless it is for some one you do not like. These are quick and cheap and very unreliable.
The twist on wire nut definitely have issues with vibration. The posi Tap connectors are good . As Don has stated The best is crimping or soldering with heat shrink
Let's see if this works. First post after introducing myself.
I decided to create a little more room in my 2017 T.C. The front 1/3 of the cargo floor is a false floor !!!
I hope this helps someone else.
Windguy,
This is the best solution:
Create an additional circuit using OEM components and methods. The AJB is easy to access. Install a fuse for your application and wire size. Doesn't get any better than this. The fuse block connectors are available on Amazon.
