Good morning. Im trying to find out if a trailer light T-connector to be installed on my 2021 Chevrolet Bolt EV, is something that does exist and is available? The lights on my trailer are all LEDs. Thanks for your help. Pierre

Hi Pierre; there are no custom wiring harnesses with a T-connector for your 2021 Chevy Bolt EV but you can use the # 119147KIT. This will still give you a 4-way connector at the rear to power your trailer's signal lights. If you're worried about splicing, the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT is another option. This clamps onto the wiring making it popular for electric vehicles like yours.

Hey Pierre, how did things go with the wiring harness for your Chevy Bolt EV? Did the option you chose power your trailer’s LED lights the way you needed? Your update could make it easier for others with the same vehicle setup.

@RobinH To be honest, I was in hospital for a surgery about replacement of my aorta valve with a mechanical one and a couple of bypass. Iv'e been quiet for almost a full year, but since the end of October 2025 I feel a hole bunch better and I will surely look at it after Holydays I keep walking and exercising at the gym and it does wonders. At 80 years old you dont want to shut any door. Thanks for the follow up Robin and have a Merry Christmas. Pierre
