Question:

Product 56077, wiring harness for 2005 Chevy uplander van. I located a wiring harness based on where the instructions said they would be, but the wiring harness didnt fit. I have read in the Q and A section that there is another locater under the cargo floor. I was wondering if there was a diagram to locate that wiring harness would be located? I can not locate any other harnesses to hook it up. Thank you.

The trailer wiring connectors on the 2005 Chevrolet Uplander should be located behind the driver's-side rear trim panel as noted in the written instructions and the linked video showing a 2006 Uplander. Some Uplander models will have a single connector and other models will have a connector already mated with another. In other words, there may not be an open connector on some vehicles and you may have to separate them to create the connection point.

If already mated to another connector, press the locking tab down and disconnect the two halves. Insert the T-connector from the harness between the two connectors that had been mated together. If there is a single (unmated) connector, mate it with the spouse T-connector end.
