GXL Black Wire. Sold by the foot.
This color wire is used a few times in the car. It is used from the #2 fuse to the Front Trunk Lighting Sub-Harness. It also goes from the front trunk lights to the clock on a 5 gauge car (even if you have a 3 gauge car the black for the clock would still be in your harness). It also goes from the fuel sending unit to the gas gauge. Depending on a 3 vs 5 gauge car will determine which gauge. There's approximately a total of 166 inches in the car with "wire to spare".
Sold by the foot.
