Need help with fuse size in cab

[gmv4k]

I'm trying to order some add-a-circuit fuses to add a transmission gauge but I'm not sure what size fuse type I need. I tried to search but only found pictures. I'm not near my truck at the moment and I would like to order parts before hand to get everything ready.

Anybody know?

After looking here are my options

Maxi fuse
ATO fuse
Mini fuse

(there are more option but these seem to be the viable options)
From

or this

But I can't tell. But I'm going to guess Maxi fuse. Can anybody confirm?

Thanks.

Thought I would update this.

ATM Add-A-Circuit 2-10a by Bussman worked for me when I was hardwiring my xm radio to the fuse box in the cab.

FYI.
