I did find one but its for the license plate light. Is that the one your thinking of?Not positive but believe there is a pigtail in the left side wiring that runs to the taillights.
I've never been a fan of those. If splicing midway on a wire, I'd rather use a noninsulated stepdown butt splice connector (put the two wires on the larger side) covered marine grade heat shrink.Im not an electrician by any means. Can you just tap into the wire using one of these guys?
