Review on 🔌 CURT 56077: Custom 4-Pin Trailer Wiring Harness for Select Pontiac Montana, Saturn Relay, Buick Terraza, Chevrolet Uplander - Vehicle-Side by Troy Robinson

The part is perfect. As for installation, you don't have to hang out of the trunk at all. Remove trunk sill. Just pull out the pin on the driver's side; the one on the right can remain as the threshold can simply be pushed to the side by tilting it. You will probably destroy the pen. You can then remove the driver's side rubber grommet and plastic trim (partially) and dig for the harness connector there. But instead of routing the trailer wiring harness under that sill, just let it out of the driver's side light instead. Two screws to remove the lamp housing, then push out the large rubber pad that has a wire running through the center. Simply pull the wire harness through the bottom edge of the hole and reinstall the spacer. Pull the strap straight down and it hangs under the van. Then just tie it to the hitch and tie it. Anyway, it worked great.
