The Curt Class I Hitch # C11527 is not a fit for your 2014 Chevrolet Trax. The # C11527 only fits the 2015-2021 of the Chevrolet Trax.
We do not have a hitch to fit your 2014. We do have trunk mounted bike racks or roof racks if you are interested. view full answer...
The Tekonsha T-Connector # 118659 you were looking at for your 2015 Chevrolet Trax includes a 15 amp fuse that gets installed in the yellow fuse holder you mentioned.
If you are needing a replacement fuse we have the Fuse Kit # PT52FR which includes 10 15 Amp fuses and multiple other fuses which are always nice to have on hand just in case.
I included a video of the # 118659 for you to take a look at. view full answer...
