GXL Green wire. Sold by the foot.
This wire is used 2 times in the harness.
1. From the Fuel Tank Unit/Fuel Sending Unit #48 to the Small Combination Gauge #24
2. The Mystery Green Wire. Not really a mystery though. This green wire is in all SWB harnesses (except possibly very early models) and was used for the Sportomatic which came out in 1968. Either way, it's in the harness.
There are a total of 353 inches in the car with "wire to spare".
Sold by the foot.
