CAN ANYONE TELL ME WHICH SIDE THE FUEL GAUGE WIRE EXIT'S THE TRUNK I'M WORKING ON A PROJECT THAT SOMEONE INSTALLED A TRUNK FLOOR THAT HAS NO HOLES ALSO DOES IT RUN ALONG THE FLOOR TO ITS EXIT POINT THANKS

I's been a few years (18).
Exits on the left side and runs up to the wheel well. It runs from the front with all the other wires on the drivers side. There should be a wire in the taillight harness. Brown if I remember correctly.
Good luck.
