Wiring harness installation on a 2017 Bolt
Wiring Harness Installation
Back when we bought Zeus we installed a hitch to add utility to the Bolt. Eventually we wanted to also install a wiring harness so we could tow a small trailer for various errands. Right after I bought the receiver I also purchased a small 5'X8' trailer and a Powered Circuit Protected Tail-light Converter to power the lights on the trailer. I would normally link to the website I purchased this on but it is no longer available. The closest I could find was this: Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector which looks very close to the one I installed here but the converter seems a little smaller (newer model?).
Anyways here are the steps I took to install the wiring harness:
|Connector and latch separated, this made testing for which wire was the correct one much easier
|Eventually I identified the tail light signal wires. The green box shows the one for the tail lights and the red one is the signal for the brake lights.
|Using the quick splice connectors I attached the tail light and brake light signal wires to the Curt module (each wire is labeled when you receive the kit).
|Everything reconnected, the ground wire was connected to the frame as well with the provided self tapping screw.
|My only complaint about the unit I bought was the left turn signal wire was too short. I had to extend it to reach the left blinker.
|Wires were fished outside of the body through this hole.
|This is the only change I had to make to the vehicle, the vent I fed the wires through was not wide enough to fit the trailer plug. I broke one off and it fit without a problem.
|Attached the provided fuse for the powered module to the battery.
|Everything fits nicely so you can hardly notice that you have a powered attachment.
