If the blue crimp goes to one side of a circuit where does the negative side go?

You probably know the answer already but this only to provide positive 12v. The negative (ground) cable will be on the item that you are trying to power up. That goes to any metal surface on the car or a negative cable if you can find one.

There are 3 different fuse sizes in this kit. One of them should fit about any car or truck with a modern fuse box. Older, vintage cars used the old glass tube fuses, so not them. I'd take a $10 chance and try them.

Am looking at the small fuse since that what my vehicle is compatible with, do you guys include 10 amp fuses?

Idr if they had 10 amp fuses but you can get them at any local parts store. They came with some small fuse adapters and some large fuse adapters. They work fantastic. Ill never splice into a line again.

Will this work for an acura mdx 2017?

It comes with 3 different size fuses so it should work for you unless you have an oddball fuse box. Check your fuses to see which one you need. I used them for a 2012 Mustang.
