???I could not find a RPO code in 67 for a low fuel warning light. Was this option available in 67? If so, where would it appear? On the dash or in the gauge package? Was it just a warning light or did it say Low Fuel? Reason I ask, I am in the process of installing a new underdash harness in my 67 Camaro. I have the gauge package on the floor console and it is a automatic. There is a connection I can't find where its goes from the harness. I have all the dash hooked up, the glove box light, ash tray light , cigarette lighter etc etc. Or is this there in case some one has it and instead of having to buy a special harness it is included in the harness.? I bought the harness through Rick's First Gen. Pretty simple to install and really cleans up the underdash.
