Apologies in advance - Tail Light Help

Hello TW

I recently installed a Mits Alloy flatbed and canopy on my Tacoma, but when unhooking the bed / removal, my driver side tail light / brake / reverse all lost power. I've changed out fuses, etc - wondering if anyone has run into this or knows what the issue may be?

 

Follow up - I have not tried to wire them to the canopy yet, still factory.

 

Did you pinch a wire?

 

Did you loose power or ground?
I didn't see your year listed, but it should be Green wires are power. Black/White are grounds.

Also, do the license plate lights work? (The use the same power/ground as the tail lights)

 

Based on the grill, it's a 2018 or 2019.

I agree, it's possible you snagged or pinched a wire.
Does that bed reuse the OEM lights? Or does it have it's own lights built into it? (a pic from the rear would've helped) Does the passengerside light work?

 

The Driver and passenger sides are joined by splices. It almost has to be a wire issue. Not a connector.
I'd start with power and ground. See what is missing. Go from there.
