I bought CURT 56327 Transit Trailer Wiring Harness as part of my camper van equipment.

Where it fits my build
On Day 104 I pulled the roof wiring through the PVC route with fish tape and brought the cable groups into the van. I fitted plastic trim around the roof opening where the wires passed through.
I also finished the remaining light-wire connections, fitted the junction-box covers, joined the remaining PVC sections and tightened the metal ties around the route.

My build notes
This stage pulled together several earlier sessions of drilling boxes, fitting glands and arranging the roof hardware. The final cable entry was the point where all those separate roof routes met.
My notes show how much of the work was physical organization: pulling cables, keeping entry points accessible and closing boxes after the connections were finished.
The route into the van was a layout problem as much as a wiring task.
Alternative products
Two alternatives to compare
The MECMO harness uses a Transit-specific T-connector layout. The CURT 59236 is a powered universal splice-in converter, so it represents a different wiring method and circuit design rather than another version of the same plug-in loom.
MECMO Transit Four-Pin Wiring Harness
This MECMO harness uses vehicle-specific T-connectors for listed Ford Transit models. It provides a four-flat trailer-light outlet.
The CURT 59236 combines a powered tail-light converter with a four-flat trailer outlet. Its universal splice-in leads provide a different installation format from a vehicle-specific T-connector harness.
