Fuse Installation for Curt T-Connector Vehicle Wiring Harness on 2019 Toyota Highlander

Question:

The install of the wiring was uneventful thanks to your videos. One problem I had was the fuse dimensions for under the hood. My 2019 highlander hybrid fuses are smaller than the 2 sizes you provided.. the larger of the 2 went in the rear with the wiring the smaller one was still larger than what the ones were in my vehicle. Thanks.

The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56217 which is a fit for a 2019 Toyota Highlander has three fuses; 1 ATC, 1 ATS, and 1 Mini. The ATC fuse goes inside the inline fuse holder on the power wire from the battery to the converter box. The ATS or Mini fuse gets installed into the engine bay fuse box in the "Towing" slot. It can be either depending on your fuse box but more often than not it's the Mini fuse. If you for some reason have another style of fuse you can check your spare fuses for this (usually on the underside of the lid) or you can obtain this from a local auto parts store.
