Review on 🚙 Enhance Your Toyota Sienna's Towing Capability with CURT 55580 Vehicle-Side Custom 4-Pin Trailer Wiring Harness by Paul Stocks

The hardest part of this build is proposing to *drill* a hole in the piece of metal for the ground wire. I've attached a photo where you can easily do this without drilling anything. The trick to attaching the ground wire grommet is to use scissors and cut the grommet and then unroll the grommet around the screw in my drawing and then tighten the grommet between the washer and the screw head. It's really easy. The wiring was just the right length and it's really easy. There is a video on YouTube on how to do this. because I was very careful not to break the rivets and the like.
