Question:
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.
